Sway bars do not control brake dive at all, they only work on side-to-side loads.
Both of my XJs have had the thicker 28mm sway bars up front, looking at my ZJ 5.9 sawybar it looks like it's a little thicker than that.. not 100% sure though. For the rear, both XJ and ZJ swaybars seem to be more of a joke than anything else. I haven't looked into it, but could be that with suitable adapter plates one could use ie. the thinner XJ front sway bar. Certainly needs some DIY brackets and some head- scratching, but that could work?
I completely understand the need for good sway bars for street use. If you're going to wheel it in any kind of uneven terrain, I highly suggest swaybar discos. Makes the ride a lot more comfy and keeps you getting somewhere instead of getting stuck at the smallest boulders
