I don't think so. The problem with washboards is that the tires are effectively in the air much of the time, so no traction. Plus they speed up a bit, and when they come down are moving a bit faster than they should be, so they spin. With 4WD, the front and back axles aren't likely to be airborne simultaneously, which keeps everything under control.
Then there's the fact that I can just buy a 4WD truck and not spend time messing with mods that may or may not work. And I get a low range to boot. Put knobby tires on it and there goes my highway mpg...
