I feel like this is a great idea and people could use this to prevent most aimbot and aimlocks. But the thing is most paid developers that provide premium scripts could easily find a workaround over this.
In my theory we could make it check if it was the same player and see if they hit directly onto the position of the part as there is a slim chance a real player would be able to hit directly onto the position of a part.
This is a very smart idea tho. Good job.
