Ohhh~! This seem cool... Here some of my ideas:
Tifa over
DeDeDe (It say it won't work on classic mode, but don't worry about that.)
Galaxy Mario over... Mario... (Sorry, I didn't know that you don't want brawl characters with change movesets...)
Dragonite over
PitTails over
MK (some of his animations are... odd... and you need to use a item hack so one of his moves aren't overpowered...)
