You know, these are based on the military MOLLE gear, which is the latest generation of WEB gear.
The system was designed primarily for GIs to carry gear. The base for the system is usually a vest or belt/suspenders (harness) setup.
The reason I mention that is that if you wanted a bug-out version, you might be able to take one of the vest or harness setups and figure out a way to strap it to a seat back.
That way instead of carrying the seat back you just undo the vest or harness and strap it on your body.
Just a thought.
