There’s this one clip where Twilight uses a spell to transform herself and the mane 6’s body into breezies, just by using the breezies’ body as a blueprint, if that spell can transform a pony into any animal, it could be possible.

I mean like an episode where it just acts like they’ve always been kirins, or dragons, or whatever, with like no justification. Like a straight-up non-canon adventure XD
