What Do you think?

I tought about another champion design but i dont know if its worth doing. So i just ask.

What Do you think about a champion that starts with a specific kit wich changes when he interacts with an elemental Dragon. Maybe one of his ablities could be that when he uses it in a dragon he changes (Look, voicover, kit). Not a complete change. Maybe like udyr. The ability could be like a beam that absorbes the soul of tha dragon or just a dmging ablity that has a different interaction on the dragon.

Pls tell me if i should Do it or not :D
