I've done this before. you have to look carfully at the back of the hub to ensure you leave enough material for the lug nuts to hold the wheel on. I was able to take 4mm of extraneous material off.
I have a friend works at a machine shop, so it didnt cost me anything. We were even able to machine with the tire on. just broke the bead so the chuck could hold the outside diameter of the wheel. but so much easier without tires.
