Inside the boom is a great idea but unfortunately I think it would be a bit
difficult as the rearmost reflector is only 1 inch from the end of the boom
and it goes right through the boom.  

It could be done but I don't think the wind loading reduction would out
weight the "pain in the butt" factor.

Appreciate the suggestion though!

How about putting them inside the boom?
