Demon vi/Aatrox/Kassadin related

As we can all see demon vi has a tail.. but aatrox whom is a demon like being doesn't have a tail. can we give him one ? also kassadins new skin cosmic reaver I have a visual request/ suggestion for that.

with each ult kassadin does his gold plating will glow more and more has he gets up to 6 stacks

also would it be possible to give aatrox a harbringer skin sits it fits his theme

has for demon vi can we not make her entire body pink
