I appreciate all the positive comments, folks.

There's virtually no readily-foreseeable benefits to becoming a different 'type' of species with a limit break other than canonical and fluff reasons. It was, however, requested
However, when used to transform an enemy instead of a character, it can be used in builds where characters have bonuses against certain species. For example, imagine a Dragoon with the 'Ancient Circle' ability, which grants the entire party bonuses to dragon-type enemies, feeling frustrated that he hasn't been FIGHTING any dragons at his low level. The limit break quality of changing a monster's type - for only one point, no less - fixes that.
