Well, transformer champion thing ?

Hi ! I just came up to an idea. First, I'm not a native english, so sorry if I do mistakes, and second, yes I'm from EUW x) Well, during UoL vs GIA, the commentators were talking about someone "pretending being a krug". Well, why not add a champion that could transform in an "non-human controlled creature" ? Frankly, this could be interesting to escape, or to surprise the enemy : You kill one of the krugs, you become one, the enemy comes, without knowing you are an "non-human controlled creature", and then, like SBLEM ON HIS FACE ! So, it's just an idea, and I'm sure you've already thought of it, so I'd appreciate other's point of view, as well as maybe Riot's one :3 Cya Skriff
