I have a Rough Country 2.5 inch lift on my 77 CJ5. The tires you see are 31's. based on the photo, would I be able to run 33's. it would only be an inch taller into the wheel wells. Most of my off reading will be seeking out fishing holes that few go to. That said who knows what the terrain will be like.
Is your lift older? Remember that the springs will start to sag over time and that will alter your clearance. I did not like the way 33's looked with my 2.5" lift so I put a 1" BL on but my CJ is a pavement queen with only light two track use. For $130 you can't really beat upgrading the stock rubber bushings with polyurethane and the extra clearance.

33x12.5 15 on wagon spoke. I did 3 .5 inch springs and .5 shackle, with tube fenders up front, it JUST cleared. In the rear, It just touched the bottom rear fender. To me, it looks like you need more lift for 33s.
It is already a handful now, so I will head you advice. I'm going to look into the body lift. How hard is it to do a body lift, and would it bring its own set of problems with it?
Body lift is straightforward apart from rusty bolts shearing off. If you take it more than 1" you will need to consider the steering shaft, brakes, clucth linkage, shifters etc etc. However all this does is raise the body, it does not make the wheel boxes any longer and you will still rub the tyres.
Also before you go for larget tyres consider the axle gearing and what you will be able to use it for and the costs.
