Actually, It sounds like a good idea. If you can get a message to Benz, or the Engeneer, my step father is a specialist in building fabric roof structures (the denver airport for instance). Basically he specializes in creating fabric (sailcloth) structures under tremendous loads (water / denver snow), and I would be more than happy to get him involved if his assistance would be helpfull.
