Has anyone ever thought of crossing over the D20 Modern campaign setting Urban Arcana with My Little Pony? If not then I have an idea that everyone's free to use.

My idea is that, somehow, the Mane Six are taken from their world to this one by the Shadow (either humanized or in their normal form, whichever works for you. I'm partial to humanization myself.) and, after a period of time, managed to regain at least part of their memories and now seek to return home while fighting off shadowkind hate groups who want to see them dead, and evil organizations who want to put their powers or knowledge to nefarious use.
