A long time ago, (30 yr?) Herb Adams had a book that said sure it can only help. The cheap and easy method he employed was to saw through the axle tube from the top, stopping before you go all the way through. Let the gap close, and weld back up. High tech is wasn't, but back then nothing was. He claimed the axles lived fine, and ran that way at the Daytone 24 hr race. The issue now is that with 335 / 30 rubber, do you really need to camber the rears? He was running 255/60's.
A lot of people discount nascar as old tech, but they are most like what we are mostly running, ie big HP, front heavy, live axle cars. They also know more about what happens throughout a turn than just about anyone because they spend large amounts of time in steady state cornering. When allowed, they run cambered axles. Is it worth the trouble for us? Not likely. As someone else mentioned, our cars already have rear tires that are proportionally oversized compared to the front. Camber is only going to make a difference when the tire is loaded maximally in a lateral direction. Unless you are running big tracks, with long sweeping turns, and you have used all the available lateral grip, you will probably never see the difference. You also might end giving up forward grip in a straight line.
