People have brought that notion up before for Smash and it hasn't been affected in any way with NoA; unless something happened recently I do not know of. At the very most they can do; is take our opinions on which VA should voice X character. Even maybe going as far as including a "language switch" option from English to Japanese people that prefer the other VAs
I.e. Falco's SF:Assault VA > Brawl's "Joey Wheeler" VA
Wolf's SF:Assault VA > Brawl's etc
Who knows, if all of us hype the potential of Dan Green being contacted by Nintendo to do Mewtwo's voice again; it would work
