Ultimate Skin idea for Kha'zix

I don't know if I am the only one, but I adore the idea of Kha'zix from a character perspective. The whole hunting prey to consume and evolve from it, taking their strength to grow stronger himself. It made me think, what if we had a skin that actually showed this in the game, rather than it just being in the back somewhere.

While I have no real idea of how it would fully work, especially design wise as I am not a designer, I think it would be incredible to have a skin where as you kill other champions as Kha'zix he would take little aspects of that champion and add them to himself as he evolves and becomes more powerful. Like killing Kayle and his wings becoming more angelic, killing Twitch and perhaps a little rat tail sprouts out, things like that. I don't even feel like the changes have to be all that radical considering how many champions there are, but the idea of getting a unique look at how Kha'zix might change for every game could insane to see and it would really bring the idea of his character alive.

It would feel like the absolute ultimate skin for him, kind of like how Spirit Guard Udyr does for, you guessed it, Udyr.

I have no more detail than that, I just felt like the concept of this was too cool not to plant somewhere hope it sparks something.
