NEW TRANSFORMATION ANIMATION???

A few champions in League of Legends have the ability to convert themselves into an animal, or a different look. I going to touch base on the animals, like Nidalee and Elise.

I had this idea about making their transformation for appealing. Its not anything big but here it is.

For Nidalee as an example, if you press r once(toggle), Nidalee will transform instantly like she does now. But if you want to go for a more natural look, holding r for 1-2 seconds will do an animation where she actually transforms into her cougar.

Any thoughts? It'll probably be hard to make and do, but it'll look amazing.
