What about a roof rack minus the rack on top? Like an exterior cage. Attach mounts at the bottom of the windshield w/ a hoop over the top of the windshield, then tabs at the top of the hoop that run down the side of the hardtop/flippac right above the door line, then a hoop over the rear windshield that mounts to the rear bumper or side of the body panels behind the rear fender. Then an option to remove everything except for the windshield hoop so you can have a light bar that can fold down or spot lights.
I always try to think of simplistic designs, the arm to rotate the awning is complex in itself, the hoop idea also seems complex. We'd prefer to design something that does the job in a more straight forward manner.
