Is It Possible To Have Custom Sound Banks for Custom Characters?

[Cahalan]

Brawl modding within the past few years has advanced quite greatly. We can add more characters to the game, include more stages by adding new slots or making them load as alternate stage, bring back our favorite characters from past games, and make the newcomers we know that would not see the light of day. But there's one thing that bugs me though: how come we can't make it to where our custom characters (think: Ridley, Dark Samus, Pichu, the like) can load their sounds from custom sound banks that do not replace another boss/character's sound file. I already know of the existence of adding sounds for other characters in the blank spaces of the original base character (See Roy and Mewtwo in PM 3.6b+), but if there existed a "Sound Bank Clone Engine" of sorts, maybe this would help those who want to add more content to an already content heavy game.
