BattleCast Volibear or VoliCloud

I know what you're thinking but hear me out. Most battlecast champions are from the void and volibear is not from the void. BUT, what if battle cast had the ability to "Consume" Other champions! Like, Battle Cast Nasus, or Riven! I think it will be pretty cool.

Now VoliCloud can just be a cloud in the shape of a bear. Whenever he uses a lightning based move, His whole body turns Black like a rain cloud. I really want a legendary skin for volibear because i'm tired of the ones that's already out. It's about time for some new ones.
