Rengarok [Skin]

So I'm a fan of puns, and I was talking to a friend and suddenly thought, I want there to be a Rengarok skin. I don't know enough about League or skins to offer any real advice on what the skin would look like. I was thinking more about the splash art. It'd be the end of the world in the background, raining hellfire, and Rengar's got flaming/smoldering hair and patches of rock in his fur. I honestly don't have much to offer for this idea except the pun, haha. Have fun with the idea!
