The barometric altimeter can be set to anything you like within its scale range, if you set another airfields 'guessed' QNH based on it's elevation at the field of departure then 1. you are on the wrong pressure setting for departure 2. the wrong setting for en route 3. the wrong setting for arrival because the pressure could have changed by then.
