Even Cowponies Get The Blues?

Okay, I just had a radical idea. Frankly I don't have time to do anything with it, because I have way too many projects going on right now. (On an unrelated note I should have a new story posted by the end of the week.) So I'm putting this out there, maybe someone with more free time can run with it cause I think it has merit. Anyways, what if we gave Even Cowgirls Get The Blues The pony treatment. Only obvious character transposition off the top of my head would be to cast Applejack as Bonanza Jellybean, but I earnestly had this idea 3 minutes ago.
