Using a fine mesh window screen just might allow crosswinds to pass through an aerodynamic motorcycle fairing, yet provide enough surface area longitudinally to retain flow attachment, much the way that louvers do such as on this car :
So has anyone tested this yet ?

The only way the louvers work is do to the fact that the area they conceal is non-aspirated.Air is pooling inside the louver,creating an environment for capturing vorticity which would allow the outer flow a 'surface' in which to skip over.
If the screen is open to a channel,the air will immediately make a right-angle turn into the void,destroying flow aft of it.
