Hey, good to know its not a completely useless idea I guess. Heres a very rough photoshop to give the idea of what Im thinking:
Im sure someone with some metalworking skills could do a complete shroud even with nice tapered trailing edges.
Might even be easier to adapt aircraft wheel fairings:

If the tapered trailing edge sat low enough it would probably even clear the body while turning and during compression
