Those with access to 3D printers could easily make this. It might need some beefing up in the area where the two connect etc.
The open-faced strut would behave much like angle iron in the airstream.I don't have that with me,but I believe that the Cd is over 1.00.
The jet created would be asymmetrical with respect to the mirrors wake and could possibly make things worse.
The mirror in free flight would be Cd 0.30 - 0.25
