I figured this would go best here rather than in Customs, since there's no actual custom made, just a brainstorm thread.
I'm starting to want to branch out of my comfort zone creating custom ponies, you know, get into some ideas I wouldn't come up with on my own. I'm sure others feel the same way! So, here's your chance--what's the one custom you've always wanted to see, but haven't yet? All gens, all formats, all themes--the world is your oyster!
