Aery Skins?

I think it would be cool if there were skin/chroma type things for some of the runes. Aery is kinda a cutesy fox spirit so it would be cool if you could change it to something like a ghoul if you were using it on Yoeick or other Shadow Isle champs. There could be a bird for Swain or Anivia.

Also definitely a dog so I can take my good boi for a walk and give him treats (souls of enemy champs)
