Karthus skin idea

So I was reading through 's Lore and I saw the end bit where it says that "When Karthus emerges from the shadow isles it is to bring the joy of death to mortals...", and when I thought about it he really seems pretty jolly in his ingame dialogue. Add in a global ult and what you get is basicly santa. He sends the "gift" of death to everyone instantly much like how Santa dilivers presents to children in one night. So can we just make Father Karthus or Santa Karthus a thing already.

EDIT: His ult should be falling presents from the sky, forgot to mention that.
