Interesting question. I would think not, unless the same model coach when moving to a one price windshield simple removed the center divider. Then some surgery and body work would allow installation of the newer one piece windshield.
From a practical perspective, I don't see where the expense and effort would be justified. However I do appreciate the desire for updated appearance.
