Seems unlikely to happen. While there are negatives to either changing the time or New England being in Eastern, there are also very big negatives to being in a different time zone from the rest of the East Coast, especially NY and being another hour removed from the West Coast. Large companies will keep de facto operating on ET.

I work for a large company and am in New England. I already regularly meet with colleagues in Europe or Asia, and it can be inconvenient but it's fine. If we were in a different timezone than New York I think people would mostly work around it rather than de facto falling back to New York time.
