tire carrier on OR-Fab rear bumper?

Hey y'all, I have an OR-Fab rear bumper and I'm trying to think of a way to fab up a spare tire carrier attachment for it. I was thinking of something that would attach at the join points of the side pieces, maybe even by bolting thru the same holes just with longer bolts, but I dunno if this would be too much force on those bolts. Does anybody on here have one of these bumpers, and if you do, have you fabbed anything like this for it? (or for a similar tube bumper?) And even if you don't/haven't I'd still love to hear your ideas.
