The Twins (a two character champ)

Mechanic ideas? I would like to see a champion that is actually two creatures/humanoids... one would behave like the Yorik Maiden... while the other is controlled by you. The abilities and catch for this champion would be that you can swap between the two creatures taking control. Abilities would let you move the creature around (a blink ability or something like that). If an enemy kills the creature you are not in, you gain some sort of advantage... so the challenge for you would be to jump out of the one about to die... and the challenge for the enemy is to catch you off guard and kill you or whittle both creatures down until he wouldn't have to worry about your advantage.... not sure what the advantage would be... to me the cool part is jumping between two characters (pretty quickly).

Lore ideas? Maybe two little goblin like creatures possessed by a spirit creature... and the spirit creature wants to have one die as a blood sacrifice and if that happens his damage output is doubled... perhaps not a spirit... perhaps the two are drones for a queen and if you kill the one she is controlling she cannot respond because you have incapacitated her... but if you kill the other she descends onto the map to attack the champion... and you get to control her... if you use an ability on an enemy champ before it dies... you can spawn another creature for you to jump to... you can only ever have two... so the lowest health drone dies.
