I'd like it under these conditions:
1. All of Fox's moves become slower and weaker by at least 30%
2. All of Sheik's moves become weaker by 50%, but Sheik gets a 20% speed boost in Smash attacks (excluding down-smash).
3. All of Falco's moves beomce slower (by 45%), but stronger (by 20%)
4. Captain Falcon's Knee Smash now kills at 120%, and his non-sweetspotted Knee Smash kills at 170%, All of Falcon's other moves get slight KB Growth nerfs (by about 30%).
5. All of Marth's sweetspotted moves do 2% less damage and the rest of his moves (aerials etc) do 10% (math percentages, not Smash percent) less damage and knockback, but Marth gets an 8% speed buff.
6. Jigglypuff's ground speed get reduced by 45%, and it's ground attacks get weakened by 50%, in addition, Jigglypuff's fair become 12% slower, and it's bair become 7% weaker. It's weight value also goes down by 20pts.
7. Peach can no longer pull stitch turnips, bombs, or beam swords. In addition, Peach's down smash get reduced to 4 hits that properly connect and do 3% each uncharged. The move also has 20% less knockback growth to balance it out.
Peach's fair also gets weakened
Peach's uair now hits two times, each hit doing 4%, and it can combo now
Peach's nair gets a 48.98% base knockback nerf
Peach's side-b gets sped up to around Smash 4 speed.
The Toad from Peach's n-b now does 4% damage and can kill at about 200%. If anyone gets hit by Toad's hitboxes, then the fungus counter will automatically initiate, but it will be 70% weaker than usual and have very low knockback growth.
8. During a grab, the Ice Climber's jab attack gets slowed and weakened by at least 58%, and Nana can only use an attack after Popo's grab attack animation ends. This is obviously, to get rid of wobbling.
In addition:
Nana now does 50% less damage than Popo, but Nana is 50% faster to balance it out. This was done so that the Ice Climber's combos wouldn't be so deadly, and so that SoPo could have some viability to him.
All of the Ice Climber's attacks are 30% faster but are 40% weaker than before.
Fair, however, is 20% slower than it was before, yet it is also 40% stronger than before.
In addition, the Ice Climber's chain grabs are gone, and replaced with throws that can always combo into any aerial that isn't fair.
9. Doctor Mario is actually slower than Mario for a change. He is slower than Mario by 50%, and is now 40% stronger and can kill 50% faster than Mario, regardless of what the ratio was before.
10. Pikachu's attacks are now 45% faster, yet now they are 10% weaker. The moves also have better trajectories, enforcing more offensive play.
In addition, Skull Bash has been slightly sped up (25%), but is now slightly weaker (35%)
11. Samus' extended grapple is gone, however, now Samus' normal grapple beam is 75% longer and by using the input that previously allowed for the extended grapple beam, Samus can now use a damaging, electrocuting grapple beam that is a multi-hit move and deals a total of 8% if all of the multi hits connect, it then ends in Samus jerking the grapple beam back and the enemy gets hit by a poweful electric strike that does 4% damage and sends the foe towards Samus, and with proper timing, Samus can follow up with some fancy attacks.
Samus' Power Missile now takes on it's Smash 4 appearance. But that's only an aesthetic change.
Samus' attacks now do 30% more damage/knockback, but are 20% slower.
Samus' weight is also 20% lower.
12. All of Ganon's moves get slight KB growth nefs (by about 30). This was done to match his nerfs to that of Falcon's, so he could stay true to his clone name.
Though Ganon's side-smash gets replaced by a sword slash that does 14% uncharged, and has good Base KB and KB Growth, being able to kill at about 110%.
Also, Skull Breaker has been nerfed up a bit to accommodate for the Knee Smash nerf.
13. Luigi is now 40% slower, and his wavedash now traverses 40% less distance than before. These things were done to make him worst than Mario.
14. The Knockback Growth on all of Mario's moves has been improved by 48%, yet his speed stats have been buffed so that he can still combo.
15. Young Link is now 30% faster.
In addition, Young Link's aerials have 32.45% less landing lag on them.
Young Link's wavedash now takes him 20% further than before.
Young Link's Arrows now do 2% flame damage (with no knockback growth) if they land on the ground and somebody touches them.
Young Link's Boomerang is now 40% more stiff, which means that you can no longer angle it as well.
16. Link's attacks are now all slightly stronger (by about 10%)
In addition, Link's dair now can spike.
Also, Link's bombs can now kill at 130%
And his Boomerang can kill at 180%, but it can still combo
Link's fully charged arrow can kill at 110%
Link's up-throw can now kill at about 140%.
17. Donkey Kong is now 30% stronger.
And Donkey Kong's bair gets replaced with a much slower, more powerful backwards punch that deals 14% damage and can kill at about 100%.
18. Yoshi's Double Jump no longer has super armor on it
However, Yoshi's up-b now takes him 40% further than before and can be used up to three times before you stop getting vertical momentum from the move.
19. Zelda's weight gets increased by 40%.
Also, The sweetspot on Zelda's moves have a 50% larger hitbox.
In addition, all of Zelda's moves received a 30% speed buff.
20. Roy's sweetspotted moves received a 25% Knockback buff, whereas his sourspotted moves received a 25% Damage buff.
All of Roy's moves are slightly faster (by 23.25%)
But Roy's weight is now 40% lower than before.
21. Mewtwo's Shadow Ball now travels 10% faster and is 10% smaller, it's pattern is also 10% less jagged.
Mewtwo's fair now has 35% more range
Mewtwo's dair now has only half of the starting lag, yet 20% more ending lag
Mewtwo's tilts now do 5% more damage and have 10% more knockback
Mewtwo can now act out of teleport with anything but another teleport (even an airdodge).
Mewtwo's Disable can now hit foes facing away from him
Mewtwo's Disable in the air now always has knockback/hitstun, and it launches opponents horizontally. It can kill at about 125%.
Mewtwo's Confusion is now much different: Mewtwo will still do the usual nigh-ee! move, but once Mewtwo grabs an opponent, he throws them forward like he would a Beam Sword or Crate (with an identical, if not the same, animation). The move does 12% damage, launches you in a horizontal direction, and can kill at 120%. One thing to note though, is if you hold up, down, or backwards before Mewtwo starts to throw the opponent, he will instead launch them upwards, downwards, or backwards, with the upwards, downwards, or backwards throwing animation respectively.
And to top it all off, all of Mewtwo's moves get a 15.00% (get it?) speed boost.
22. Mr.Game&Watch can now L-Cancel all of his aerials.
GameWatch's moves are now all 20% faster and 34% stronger.
GameWatch's uair now has a windbox (i'll get to that later).
GameWatch can now absorb his own patties for a quick bucket, yet the patties don't hurt him, the downside is that a patty-filled Oil Panic only deals minimal damage, and it has poor knockback stats.
GameWatch's dair can now spike easier and it is 40% stronger (compared to vanilla GameWatch) all around.
GameWatch's throws can actually kill now. They kill at about 150%.
GameWatch's vertical momentum no longer gets cancelled when using his n-b.

26. Kirby's throws can no longer be escaped anymore, and they can combo.
Kirby's up-throw can kill at 120% now.
Kirby's inhale has now been changed up: When Kirby inhales a foe, if he presses A, they will get released as normal, only the move can actually combo now. If Kirby presses B, he'll copy both the opponent's Neutral Special and their Side Special. And if Kirby presses Down on the analog stick, he'll copy both the opponent's Up Special and their Down Special.
Kirby's attacks are now 40% stronger and 30% faster. In addition, Kirby's air speed is now 12% faster, allowing him to keep up with his targets for combos.
Also some of the following return from Smash Wii U:
Autolink angle
Windboxes
Red Lightning when you are about to die
That bouncing effect that occurs when you are spiked or meteored and land on the ground
The removal of Meteor/Spike cancelling
All of the Pivot Techniques (although they're easier to use)
All of the extra Smash 4 characters, only Melee-ized
The Custom Stage feature, which will be a combination of Brawl's and Smash 4's, with a few unique thing in the mix
Online Mode
For Fun
For Glory (only most-all of the omega stages will have platforms and different layouts, in addition, with some stages, the platforms will actually move around, identically to that of Smashville's and other stages with balanced moving platforms)
The ability to vote on stages to fight on in wifi battles (like in Brawl)
The ability to play custom stages against your friends
All of the extra Smash 4 stages only balanced.
-----
Also, Melee's stages will be balanced but fun too. And don't worry, the speed/depth/wavedashing/l-cancelling/dashdancing will still be in the game.
