Probably not. Tuft testing would tell if there is a positive effect, but won't quantify it.
My guess is that attaching a leaf blower to the vent might. The blue area reaches halfway up the windshield and out onto the hood. There's a lot of air moving through the high pressure zone with maybe a little bale of rotating air right at the base. The air an inch or so off the surface is being flattened by the onrushing volume of air.
