Lee Sin - Revert Last R Damage Buff, Exchange for QoL Buff Instead

So, was wondering if it would be possible to change Lee's ultimate so that if the target dies they aren't completely removed from the game. So instead the dead body is kicked back to it's maximum knockback range first~~ before exploding into a a billion pieces and applying a 3.5s Fear to all nearby targets directly around the blast radius who were facing the primary target before they detonated otherwise slowing them for the same duration~~.

This would allow you to use low health targets you've already used a Q on to displace yourself if Q2 was used fast enough i.e. you could now also ride/fly with the target whilst they were still flying through the air despite already being dead. It would also keep the knockup effect on secondary targets intact. Thoughts? xP
