Hybrid Champs

Dual scaling champs are pretty cool, like Jax and Kai'sa (even tho she busted rn) but...

Wouldn't it be cool to have a champion that can change their damage type at will? Or maybe this would be too broken? Let me know your thoughts.

Since we have camille's passive where she can gain defensive stats based on the damage affecting her I figured this concept can be applied offensively to a champion.
