Stiffen Rear Frame?

01 4 door XJ.

I'm looking for a way to stiffen up the rear cargo area/rear hatch area of my XJ.

I was out wheeling last night and stopped on a really flexed spot (I was checking suspension component clearance/etc. after making changes). I opened the rear hatch to get something and then couldn't get the rear hatch to close correctly (it latched fine after I got back on flatter ground).

Now yes, the simple answer is "don't open the rear hatch when the body is flexed out" but I'm taking this "issue" as an indicator that the rear of the body is twisting and that's something I'd like to prevent (less twist = longer lasting body).

I've already done 3/16" welded frame stiffeners from front to back. I'm thinking of welding a piece of 3/16" plate on the back side (fuel tank side) of the rear crossmember (where the bumper bolts onto). If anyone else has some suggestions/experience in stiffening the cargo area, I'd appreciate the insight. I'm trying to avoid a cage as it's also a daily driver and I don't want to loose the versatility.
