Air curtain would be fun to make. I'm still adding the crude mods to the car though. Walk before run.

We know ducted air curtains work. They're showing up on more and more conventional vehicles. The trouble with DIYing stuff like that is I bet the improvement is relatively small, which makes it hard (without a wind tunnel) to know if you made things slightly better, worse ... or no change.
