It's not impossible,but not 'practical' unless you finished my trailer for me and pulled it around behind all the time on the open road.
You'd most likely need to remove the entire roof and greenhouse and begin fresh,a daunting task.
If you will go to GOOGLE IMAGES and search for the MG EX 181and GM Sunraycer,these will give you an idea of what Cd 0.117 would look like.

hi, thanks for the calcs!
the mpg figures i'd like are in UK gallons so not that bad.
I'm doing 40.2mpg uk according to the onboard just now
I'll not be aiming for such a drastic Cd reduction, but looking for practical options that will enhance the car's aero performance and help to increase mpg
