Also a Bonneville spoiler with endplates constitutes the top half of a boxed cavity.

True, but in this application it's next closet cousin could be a tonneau cover on a pick-up truck.
If they wanted down-force out of it I'm sure all they would have to do is add a wickerbill/Gurney flap rear spoiler on it (as on my truck). Lots of drag, lots of down-force.
