Automotive base bleed a.k.a. running a duct(s) from a higher pressure area to the back to "fill" the trailing wake. It has been discussed. IMHO if you have the excess space in the vehicle envelope for ducts, you could chop the top and do even better because ducts have their own drag. But what do I know; I haven't tested it and aero ducts in other places are enjoying some popularity.
