If they did one about Leo it would most likely be in a format to explain the extra stories about himself, Kefka, Celes, Cid, Terra and the empires early war campaigns and magitek studies. It would work fine if done, but seeing as FF6 has not been remade for a newer console I seriously doubt a spin off will be in the works for a long long time, if ever. I'm not opposed to a spin off, because it's not like it's gonna hurt the original one way or the other. FF6 is gold and any future spin off mess ups can stand alone as their own blunder. Yet, an awesome spin off would rock!
