So maybe you could use dimples on fairings, fuselage or struts,

if the struts are circular tubing, eh?

Could be. Somewhere or another I saw some wind tunnel data on golf balls
that nicely showed how the flow remained attached further around the back
side (no spin was involved - just a reduction in the wake). But you would
have to find out what the range of Reynolds number this works for...

I've seen a video of that, but don't recall where. However, I believe that
you have it backward--the flow detaches earlier (from the non-spinning golf
ball) and reduces the drag.

I am not quite sure how that might relate to wings and propellers; but I
suspect that they (wings and props) are two radically different, and
possibly opposite, phenomena.
