I think that cartoon style would give Brawl a new touch. He has a great chance to be in, along with Midna.
And here is part of a moveset I think would be cool.
---------------------------------------------
B moves
B: Boomerang. If you hold the B button, you can control it for a short time. It can be canceled if you release the button.
B>: Gust Jar. He can suck projectiles and items, and throw them back.
Bv: Skull Hammer. Link puts away his sword and uses the Hammer instead. It is slower but obviously more powerful.
B up: Deku Leaf. It works as Peach's parasol, and in the ground it blows people away.
Tether Recovery and Grabs
With the Grappling Hook
Taunt:
1. He swings the Wind Waker
2. The hat transforms into Ezlo and they do something like this :

3. I don't know... any suggestions? It should be something of PH but I haven't played it, so idk what it could be.
Final Smash (They are somehow bad, I couldn't think of some good ones)
The other 3 Links appear (from Four Swords) and attack the enemies. OR
The stage gets fludded and a hurricane appears, you are able to control it .
On-screen appearance
A whirlwind or the bird from Minish Cap that transported you when you played the ocarina take WWLink into the stage.
Optional
He could glide with the Roc's Cape, but it would be wierd.
---------------------------------------------
What do you think? It can be modified to include something of PH. I saw a video in which he was using the Boomerang, and you could draw its trajectory. Thats why I included it
