Is this possible?
Is it okay if I make it?
How should I go about with the coding? (As in how does Pixelmon handle shinies-- can I make them spawn like that, but with highly increased rates etc?)
Are there any color combos in specific anyone would like?
I'm ASSUMING I'd just make more folders for each color combo in the texture files and put in the edited textures then have the code it in as selecting randomly from one of the folders each time a pokemon spawns.
