negative-nancys just kill me...such a downer-debbie. obviously whatever material that was used for the core didnt ahve camber before it became a ski, so if a ski can be pressed to have camber and last a few years, then its possible to heat and press a ski to have reverse camber and last a while. all probably depends on how long you leave them in the andrewT method, and how many times you heat them. just a little input to those doing the project: i would say once you reach the point where they are reverse camber-ed enough, just leave them being pressed to that point for a week or so with heating however often you want. just makesure you leave them being pressed for as long as possible even if it isnt making them more reverse cambered.
