Mother of shadows [champion concept]

I had an intresting idea for a champion; she would be a minion/summoner themed mage who's abilites bring to life shadows and feeds them with her lifeforce ( each minion could drain X health ) and it would be almost like the shadows are her children and they could look like children and her ult could be she rips the shadow from an enemy champion making it fight for her for a few seconds. I think this sort of champion would be very fun and there isn't an champions themed like her or many minion/pet champions and i'd love if it was made into an actual playable champion so much :D
