I don't care much about the characters, just the level design.
I think you should just forget about the characters and just use Sonic, Tails, Knuckles and some of the cast. But that's just coming from me.
Here's some characters that I would recommend.
Playable characters:
Donkey Kong: Sonic
Diddy Kong: Tails
Lanky Kong: ?
Tiny Kong: Amy
Chunky Kong: Knuckles
Non-playable characters:
Cranky Kong: Uncle Chuck
Funky Kong: Rotor
Candy Kong: Rouge
Snide: Antoine
Wrinkly Kong: Queen Aleena
K. Lumsy: Big
Troff 'N' Scoff: ?
Squawks: Flicky
