Suggestion Towards Lee Sin's Ultimate

So I was thinking since the ad ratio is kinda op, and most uses of his ultimate is used as an execution rather than using it for utility or for a skillshot, I was thinking that perhaps if they were to have the ult reapply half the damage of the initial kick on collision with enemy champion would make a means for the balance team to take damage out of his ult but still have the ult be extremely rewarding as a finisher, this way the ult can do an extremely large amount of damage if aimed well, but if not, it can do a lower amount instead.
