Interesting idea to overlap the roof aluminum on top of the hurricane hinge. I've never seen it done. I suspect it's more hassle than it's worth. Yes, it takes advantage of the shingle principle, but it looks 10x better and it's 10x easier to put the hurricane hinge on top. Plus, if/when your teardrop needs maintenance, do you really want to have to remove a roof panel just to reseal/replace/tweak the hinge?
It's not hard to seal the overlap between the hinge and the roof. Butyl tape, hot-melt glue, 3M 5200, Sashco Lexel, EPDM gasket, 3M VHB tape ... pick your poison.
