I think it's like using a trim tab on an airplane to offset wind variations. If the boat has proper neutral bouyancy then any change is going to involve pressures amounting to only a few pounds. The periscope could concievably offset that.
On the other hand, it sounds good during a test, but I don't think it would be much of a combat tactic.
