R6S style bulletholes

So, i have been having trouble getting ideas for how to execute this.

Is there any sort of way to detect if a union has a portion cut from the rest and have it fall, or is this too big of a task for roblox?

what i want to happen: if you shoot out a circle in a wall, the wall will reveal a large hole in the shape you shot it in

PS: if anyone knows, if someone draws something innappropriate using it, would that get me banned?
