What would be the effect if 2 identical drivers are connected in parallel but one of the drivers has its magnet orientation in reverse. Would 'nt they move acoustically in phase but electrically out of phase. Would they still benefit from the advantages of push-pull drivers?

You could also reverse the pole of one the two speakers, same effect.
They still benefit push pull configuration.
