I want that.... XJs on full-widths and Boggers are so awesome. What did you use for your hood vents? I like them... they don't stand out as bad as some others I've seen.
Honestly, the one thing preventing me from upgrading my suspension to a long arm setup is the fact that I'd be able to tackle more challenging stuff. Which means that, as you said, a rollover is bound to happen. I agree with the saftey first. Go for the cage first.
I love 2 door XJ's. Good platform to start on. Make sure there's no rust in the cargo area under the carpet, and under the rear seats. They're famous for that. Can't wait to see the progress on this one.
