I present the same question to you then. We have two Capcom characters, why shouldn't get more of those?
I'm fine with more Capcom characters in Smash if those characters have history with Nintendo...
Arthur from Ghosts 'n Goblins games, Mike Haggar from Final Fight games, and Ryu from Breath of Fire games would be sweet.
I'm also fine with Konami characters who have history with Nintendo...
Simon Belmont from Castlevania games, Bomberman from Bomberman games, and Goemon from Ganbare Goemon games would be amazing... I guess Snake can come back...
Man, I wish Nintendo would make Smash spin-off games featuring third-party companies...
