Fallout Ponies?

Hey there amigos! For the past few days I've been doing something that has nothing to do with updating Sky's Changing Secret, I've been building a Fallout and MLP crossover fic's universe. On the first day, I was entirely convinced that I was not gonna try a Fallout Equestria side fic, but now I wonder whether or not I should use the Universe I'm creating or whether I should try a FO:E side fic. I'd like all of y'all's opinion on this idea of mine. I will definitely keep trying to update SCS but I can't keep myself from wanting to write a Fallout crossover.
