This is similar to what I have in mind for my hatchback. I have welded up the support that plugs into the hitch but that is as far as I have gotten. I am going to leave the top lower than the top of the hatch glass to leave a space to see out of. It's not quite as clean aerodynamically but I should get some of the benefit, especially if the sides are at the correct angles and the top intersects with the template. The top could be hinged to allow normal function of the hatch.
