Is it possible to replace the Crowd Chants?

Cool thought I had watching the project meme/slam whatever video where they have an audio overlay of the crown cheering Mango's name. Would it be possible to replace the crowd cheers with other custom chants, like pros affiliated with that character instead of the vanilla name chants?

It's possible, yes, and easy too. I can't test it now because my PC is dead, but if you have ever used SuperSawnds, the crowd cheer is one of the first 10~12 sounds on each character.
I don't see any point in changing them, personally. None of my friends are into competitive smash, and it would only confuse them.
