The problem is those 10k votes aren't going to move in lockstep from one character to another because different people gravitate to different characters. If Ryu Hayabusa gets in, some of that support may shift to another NES character, but not everyone who support Hayabusa does so because of his NES games. Some, for instance, might move to Dante, for being in a similar genre. Some might move to Ryza, for being from the same company. Some might move to Scorpion, because they like ninjas. Some might move to a character from Level-5 or Falcom, for being from an unrepresented company.
Voters aren't a monolith.
