I think if Sean were to make it back into the game, he would need a redesign, at least with some of his outfit. "Dude in a gi" is already perfectly well covered by Ryu and inevitably Akuma. They've already been talking about characters' individuality being a big thing and wanting everybody to look and feel unique, to the point that they altered Ken's design quite a bit, and he's been someone that looked the same since...basically since as long as he existed.
It wouldn't need to be too drastic, but maybe take some of the ideas of his design and just expand on it a little. Instead of a yellow gi and pants, maybe a yellow jersey and some training pants or long shorts, he could even retain the black belt if he wanted. Basketball shot works decently as a V-skill, since you could only have one out at a time and the setup of the ball coming in from offscreen and him actually shooting it gives enough of a delay that it's only really a setup tool instead of a pressure projectile like the hadouken or sonic boom. Otherwise I'd say the basketball could be his V-trigger, but you'd have to make it unblockable or something to ever make that worthwhile. I don't know.
What I do know is that if Sean ever does make a return, he'd better damn well still yell TORNAAAADE!
