Another thing I got to thinking about in the shower (**** you for getting me thinking) is aerodynamic flutter. I'm afraid that the rapidly reversing airflow would induce flutter in the vanes. Make them rigid enough to resist it and they would probably end up so thick that they displace enough air in the port to negate their benefit. The design work that would have to go into the cross-sectional profile would be prohibitive as well I would surmise. Might make a good final project for a aero eng or some such major.
