A Karthus Skin I'd like to see this Harrowing

I'd really like to see a ghost bride Karthus this year. It would be really funny to hear his scream turn into a wail of sorrow. His Ult to turn into a weird light to heaven-esque appearance. His wall be a flower trellis , Q will pop flowers, and E will be a rose garden or something. This past joke skins were just fun and funny and I'd like to see 1 skin that is very much a costume skin for the Harrowing.
