I can relate to your question, my old rims had a small lip at the edge that the head of the screw hit first. It never cause a problem just looked like the screws were loose. 40 years ago I had a set of mag wheels that used large pop rivets instead of screws, they stuck through the rim about a 1/4" . When the slick was removed the rivets had imbedded into the bead and held just like a screw . No broken screws, no screws unscrewing and no fighting trying to screw the screws into the tire bead. Just a thought of something different.
