The current Smash Bros 4 Roster, except Lucina and Dark Pit are semi-clones instead or just more unique in general. I would also add the following characters and some changes they could have gotten in:
- Ice Climbers (Tweaked to avoid some... Certain issues they had in Brawl.)
- Lucas (Tweak him as well and change up a few moves.)
- Wolf (He's pretty fine as he is, though maybe he could use a bit of fine tuning on parts of his moveset)
- Roy (Has his Fire Emblem Awakening appearance. Would have a mostly overhauled moveset and some modified attributes. Of course he keeps the fire and an improved Flare Blade move... It's not Roy without the fire after all. He's our boy, we cannot leave him behind.)
- Chrom (Would sort of be like an Ike/Marth mix with some of his own unique moves as well. Would have an Ike colored alternate costume. lel. Plus, the reasoning for not including him has been contradicted.)
- Mewtwo (Give him some major improvements to some of his moves and attributes. He's not a lightweight at all.

)
- Some kind of Grass Type Pokemon to go alongside Charizard and Greninja.
- Dr. Luigi
I may have forgotten a few, but those are a few I can name.
