I have dual role bars so pretty much the same setup as you but mine is a BDR. I cut a piece of Lexan to fit the outside edges of my bars and extend all the way across with 1/2" or less gap all the way across. To test the idea, I just used large wire ties to attach it. As for how it worked..................... it's hanging in my garage collecting dust. It changed the wind pattern through the car but really didn't cut the VOLUME much at all.
