Zac Needs More Skins

I don't personally play Zac (or play league that much at all) but I've noticed he doesn't really have a ton of skins and I was hoping to through some ideas out into the internet to see if anyone out there wants to do something about it (mainly riot or artists who can draw my ideas). I can understand that making skins for Zac would be tough since you can really only change the color of the gloop so many times before people get bored. I was thinking of an Egyptian skin with Zac being made out of sand. This seems like a plausible idea to me and I could also see it being a popular skin. I also had the idea of using mud or something similar and doing a swamp Zac or even something like Teemos' Omega Squad skin. I could also see the use of lava or magma in a skin for him. Those are my ideas I'm curious to see what others think.
