Idea for a passive: Heal allies after you die (without requiring Redemption item)

I was playing as Uther in HotS, and his trait/passive is that he can heal allies for a short time after he dies. No Champion in League has this, though does allow you to do it if you opt into it. Having it as part of a Support Champion's baseline kit, however, would be an intriguing addition, and would certainly be something new to add to the game.
