Fluted channels also add surface area, increasing the surface area of the boundary layer. So does a fin. In addition the fin could add torque to the fork/wheel/bar assembly in case of a crosswind. In case of a partial headwind (direction of wind velocity is not parallel to the direction of bike velocity), the laminar flow along the channels would be joined by some lateral flow across the channels. Would this component be turbulent? I dunno, but it's certainly not clear the channels or fins would do any good, at least not to me.
I do keep thinking that in combination with a front fender extension like Jan has talked about, a fitted back section of the front fender could direct the air as it comes off the tire/rim so it flows behind the fender rather than behind the tire. Somewhat like Zip's idea in integrating the shapes of their aero tubular rim and their own tubular tire.
