What would be some great new Smash Brothers characters?

I would actually like a full blown Vs. version of Smash Bros. One publisher vs. another. Maybe a Smash Bros. vs. Capcom or Smash Bros vs. SEGA lineup with an equal split between mascots. Nintendo could slim down to their best 15-20 characters and add in an equal amount from the others'. I just don't have too many more first party characters that interest me anymoe to play that aren't already in the game and judging by most eveyone's suggestions in here, many feel the same way. Here would be some possible choices if done with Capcom:

Arthur(Ghouls N Ghosts)
Mega Man
Buster Bros.(Can be a duo like the Ice Climbers)
Chris Redfield(Resident Evil)
Zero(Mega Man X)
Super Joe(Bionic Commando)
Ryu
M. Bison
Captain Commando
Strider
Mike Haggar(Final Fight)
Dante(Devil May Cry)
Joe(Viewtiful Joe)
Amaterasu(Okami)
Phoenix Wright(I don't know how well this would work but it could be fun. His moves could be word bubbles thrown towards enemies)

Capcom probably has more characters to pull from than Nintendo itself.

unless you go back to the old school libary avaliable to them
