Plenty of the XJ guys are missing rocker panels and those are an even weaker uniframe. I'd say it's very negligible.
The uniframe is inboard about 10" from the rockers. The outer rockers lend support to the floor that goes beyond the "frame" rail, which is also where the outer seats are connected and body weight is pushing down, as well as gives support when stepping on the door sill area. I'll bet if you rode in one of those rusted out XJ Heeps, you'll feel like you're taking your life into your own hands.
