Yup.

I like that last beetle overlay, on the left, don't know about the nozzles though, rather keep it simple.
The nozzles (active or passive) capitalize on having engine cooling air at the bottom rear. A front engine car would lose pressure in a long duct.

With a bit of adjustment it could be blended well into the body, and doesn't overhang and affect manouvering.
My modelling skills don't support the blending you seek. That's the thought experiment, though; how to minimize the additional length.

NeilBlanchard -- the overlap of those two red outlines is similar to the correct aeroform, but needs to be slid back about 1/3 vehicle length for below the beltline (lacking the narrowed rear track ), and is ~7/6 too wide for above the beltline.

Edit: Tesla, weren't you talking about a trailer? That could spin off as a new thread.

No Coanda nozzles for you! How about a compound curve cap that hinges up like a trunk lid, over sliding van doors that meet each other at the apex of the boat-tail?
