New champion idea

We are preparing for a new champ. Looking forward to it. But with all the champs we currently have that can use shadows to now you see me now you don't to being able to pass through units. So...how about a champion that can clone another champ ? I think it would be a game changer. Think you call for help and jg shows up to see a double, who is the real offender? This champ would when cloned take on that champ ability as well. I think it would be interesting.
