[Skin Concept] Snowdown Skins from the Shadow Isles

Maokia seems to be the only shadow isles champ with a memorable snowdown/winter holiday skin. I was thinking that caroler karthus would be easy enough. Also, they could do something interesting with a reindeer hecarim.. And decorater thresh where his chain is a string of lights and his lantern is a tree topper could have some special interaction with Mao...

What do you guys think? Good ideas? Bad ideas? Things best left to rito? Anyone got any other ideas?
