RATS! I was looking forward to a chop & taper thread.
But... nice vert find, though. I guess.

Now the plan so far is tube chassis the vert and lighten it as much as possible and stick my xfi drivetrain in it.

Well, that alone will make it a one-off.

I have no idea what the aerodynamics of a convertible are compared to a hatchback car

Unfortunately: worse. You get separation at the windshield (when the top's down), the widest part of the greenhouse. No tapering benefits of the top or sides of the hatchback body.
That said, the reason you get a convertible is to enjoy the open air, right? So in the fine part of the year, just enjoy it & know you've done your best in the drivetrian and weight departments.
But for winter use... you could fabricate a sloping canopy top that would be at least as good as the chopped & tapered hatchback roof.
So, you get to enjoy the summer al fresco, and then when the weather turns to crap, take comfort from the fact that at least you've got superior winter time aerodynamics.
