How to reduce drag of surfboard roof racks?

Note from MetroMPG: this thread split off from Roof rack test: quantifying the aero penalty
Is it possible to decrease the drag on a roof rack? I'm a surfer and I own a 2001 Civic coupe so the roof rack isn't easy to take on/off. It uses some arms that I'm considering on streamlining.. Basically, this is my first post as a new member/former lurker.

I have a fairing but I want to get rid of it due to all the noise it makes, I thought of applying some of those tornado generators that you see on the Lancer Evo on the back of the roof. I also saw some aero bar fairings that I could trim to go on either side of my pads (I need the pads for my surfboard). I drive conservatively and average about 32-34mpg right now with the roof rack (epa is 29mpg) and I'm continuing on improving my hypermiler driving.
