/Toggle skins?

Since Dj Sona came out with her ability to change skin by typing in /toggle or Ctrl+5, im kind of interested in other /toggle skin ideas riot could come up with. For example, what about elemental Xerath? /Toggle could change his electric element to ice, wind, earth, fire and water. They could add more but that's just an idea. Could riot make more /toggle skins? Or would there be too little Champion skin ideas to add /toggle to...?
