Can we design a champion that can remove disables.

We all know the story about how Sylas is supposed to be a prisoner and yaddie yadda breaking his chains and what not. But this got me thinking. We have a lot of champs with shields and heals but not a single champ (that I know of, correct me if I'm wrong) with the ability to break a stun. What if we designed a champion that had the ability to for example undo Morgana's root, but make it so the disable removal was temporary (because otherwise he or she would be a God). It would be an interesting ability with a serious repercussion and vulnerability if used too soon or at the wrong time or amount of health. Discussion and thoughts?
