So I did finish screwing in the new ceiling. I did not use rivets. Screws were originally used with emergency hatch so I figured I'd just replace with similar screws. It did compress as in demacs case but mine was already dried and rain tested between first dynaflexing it and screwing. No leaks. Hasn't leaked since adding screws either. The weights were only because I didn't screw it in before drying. If it survived a rain uncompressed it's going to survive one compressed imo.
