Great idea, but would also entice a lot of cheating. Imagine you see a teamfight going wrong and you try to DC. That's no fun for the opposing team. Even worse for champs as Karthus who can DC in the middle of a teamfight and still do tons of damage while being unkillable.

Also situations like your opponent is DCd in his jungle and you pass by. You do not kill him, because he is DCd, but if he reconnects he can instantly gib you.
