As far as bike engine goes, the 2 issues are that 1. Motorcycle clutch is no good for starting a car 2. No reverse. Both are fixed by using a car transmission, but getting the motorcycle engine to mate to a normal car transmission takes a lot of fabrication. Best to just stick with a proven FWD drivetrain the way Elise/Exige/Evora/MR2 does. The one thing that will need some modification is the shifter linkage.

Same width rear track, sunken in ducts on the sides should be good. If you're going to have a bit of tail hanging out you'll be able to enjoy a lot of drag reduction already compared to typical cars, which have short rear overhangs for various reasons. On my MR2 Spyder the side ducts are sunken in at around the maximum angle possible.

You'll have the chance to design the ducting to pass air through the engine bay much more freely than on my MR2, so be sure to do that. Since some of the air on the side will be diverted to the engine bay, I think you can taper the greenhouse portion more.
I've pretty much given up on the motorcycle idea for these reasons. Thank's for the tips about the air ducts
