basically impossible. Lift or downforce is created by air having to travel at different speeds around an object. The slower air is at a higher pressure than the faster moving air giving a net force. to alter air's speed, it must encounter added surface friction or have it's direction changed through some force imposed by the surface of the vehicle.

The more you work toward a net-zero drag/lift situation at speed, the more you will reduce drag, although I would always err on the side of downforce.

I'm planning on doing a boattail *someday* and lift is my biggest concern, currently.
