Interesting idea, but I doubt that it would happen. It's totally subjective, but the full-season Minor League schedule of 140 games seems to be just about perfect. The regular season runs from mid-April through the Labor Day weekend. Postseason is finished in mid-September, which is still a "Fall Classic" of sorts. I wouldn't mind moving back to a 154 game schedule. However, I'd imagine that even a shortened season would still run within the same current timeframe in order to add more days off. So weather would remain an issue and World Series games would still run up to Halloween.
