Shaco E idea - small rework

something I thought of while I was musing about missing old Shaco and how to do him justice in the future

What if his E, instead of being a simple point-click execute button, was a prep instead? So my idea is, he clicks E on you, and wherever it lands on your champ model it sticks in and becomes a 'weak point,' - think Fiora vitals - and then his next auto consumes the spot and if he hits you on that weak point he does a lot more damage than hitting you anywhere else

so it would give him a more clear win condition in his fights (get himself onto that spot and proc it), more counterplay (wall hug, he has to open with E instead of Q and thus making you aware of his presence, etc) while maintaining or even emphasizing his mind game nature indirectly, since good box/clone usage would make or break his ability to pop you now

I think this would be something that would make me want to play him again, the potential for it is pretty neat, I feel
