If you're prepared to spend anywhere from $250 (about the starting price of many aftermarket bumpers) to around $550-$800 (most upper end bumpers) then, it would be a simple to just purchase a riser for your receiver to keep your towbar relatively level and, that way you'd not have to worry about trying to find an aftermarket bumper that could concieveably be mounted, along with a base plate.
If you want to "dress up" your Jeeps looks, then having both on there won't help too much in the looks department. Many of these aftermarket bumper manufacturers have done quite a bit of streamlining in their lineup of bumpers for that reason, to keep things looking way nicer than factory bumpers and, still keeping prime functionality in focus too.
A riser might cost you oh, say, $50-$75 or so. You most likely can get easily double that for your base plate. So, you'd make money on that, to apply to your new bumper.
Now, where it will cost you a bit more is, the adapters needed attaching your present tow bar, to the recovery tabs on your new bumper. There's deals to be had on those too, if you look in the right spots. Good luck.
