I don't have a real world application for this so I guess it goes in the hypothetical column. If you had a car with a sloping rear but it sloped beyond the "template" could a gain be made by raising the rear (and possibly lowering the front) to better conform to the template? It would increase the height and I assume punch a bigger hole in the air but would there be any gain from better airflow over the top? Just a thought. Probably a simple answer but I like to try and learn when I can.

These are about the only real world examples I can think of.
