That's actually a great idea! Gives it a real personal twist. He ever even got the chance to be a wonderbolt, but does this dampen his spirit? No. Because he still have 4 hooves and the wide world of equestria to see. I just picture that the sword of his cutie mark represents determination and the wings would represent freedom to go and explore as he pleases. Very epic in my head haha. But sure to take some notes about here he's from, growing up, let us know some background too. Not just one drastic event with a random pony, just doesn't feel to real.
