What if shaco had execution damage on his w and/or e

This honestly something I'm not even sure should happen but I just can't help but post the idea and see what people think. Dying from a laughing box just fits his theme so well so giving it execution damage just sounds perfect theme wise but could be broken. IMO if they did give his e execution damage I would only expect to only apply if it hit the back.

Couldn't help posting this after playing a game as shaco where I died but my box from earlier combined with brand passive killed the enemy shyvana, just laughed and had a permant smile after that
