"SEGA All Stars Knock Out?"

I'm sure many of you are familiar with my Sega fighting game idea that I posted at IMT and ... some other forum.

But anyways, I figured I'd post it here too and get some feedback and suggestions for stuff. Right now the roster is in teams not unlike SFxT. Here's what I got so far:

Sonic the Hedgehog - Miles "Tails" Prower
Knuckles the Echidna - Amy Rose
Akira Yuki - Sarah Bryant
Axel Stone - Blaze Fielding
Ristar - NiGHTs
Beat - Sketch Turner
Ulala - Amigo
Gilius Thunderhead - Tyris Flare
Joe Musashi - Altered Beast
Alex Kidd - Billy Hatcher
Vectorman - Warhead
Ryo Hazuki - Wuying Ren
G - The Magican
ToeJam - Earl
Red - Blue
Sakura Shinguji - Ichigo Ogami
Pulseman - Bonanza Bros

Dr Eggman - Nack the Weasel (Mid-Boss)
Death Adder (Main Boss)

CHARS NEED OF PARTNER
Selvaria Bles
Jack Cayman
Bayonetta
Vyse
Nei

Wuying Ren Would probably be a good partner for Ryo.

Also you should add The Guys from House of the Dead 2
Agents James Taylor and Gary Stewart

I'll consider the agents. But thanks for the partner for Ryo
