4 Horsemen Hecarim Skins

I know he is basically is based off of the 4 horsemen, mainly war, I feel like it would be cool to have skins based off of each horseman. For Pestilence give him a green tint, with a more diseased like look and flies around him. The ult could be a bunch of flies or something For Death make him skeletal with a skeleton horse body as well. For Famine a black tint with a scale on a stick as his ax. Ult could have something to do with locusts or something. For War give him a red tint or deck him out in armor.
