New Karthus Skin Ideas 2016

Just remarking on the oustanding groups of skins league already has (Project, Blood Moon, Pool Party, etc.); I wonder what it would take to put Karthus into a group of champions to receive a new skin? Now obviously "Pool Party Karthus" has some conceptual flaws but something like "Darkstar Karthus" sounds like an intricate piece with incredible aesthetic value. Or Blood Moon Karthus in the Kabuki fashion. Or even an Arclight Karthus playing on the concept of him bringing followers/victims into the light. Now this is biased as I play Karthus almost exclusively but I really do think there's so much room to capitalize on his concept and existing particles. I'm excite to hear what you all think, I welcome any response and thank you all for listening.
