I'd bet if you had a really nice, efficient airfoil section, you may not have to pay too high of an aerodynamic tarrif to get the requisite amount of lift.
Also no document found but based on the info at hand I'm going with crackpot idea. Not to mention dangerous since downforce is the friend of handling. That would suggest anything lifting is an enemy of handling. Probably similar to hydroplaning on dry pavement.
