Full Size spare rack 2001 Cherokee

When I went to the dealership to look for a rear exterior full sized spare rack, they said those are no longer made for cherokees. They are made for liberties and wranglers I think. Is it possible to rig a wrangler rack to a cherokee? Is it possible to do without drilling into the car or damaging the paint? Right now the full sized spare sits in the cargo area. Would it also be possible to somehow rig the bar that the donut rests on to a full sized spare so it lays against the side wall in the cargo area? Thanks alot.
