Dollmaker was written in Flash, perhaps you could have something like that.

Sprites would be made from layers that would render on top of each other and compress to make a single sprite image of your character, like a character creation screen. Then you could select a list of basic powers for your character, and then type in a name. Species would be already intact with the sprite maker, and would have the basic families of species.

That's just my idea though, it would make it a lot easier than to ask people if they want their characters in the game code.
