Still very much a work in progress, but I'm not really buying any argument against Greater New England.
Which is what I've been trying to tell you all night. A commonwealth consisting of New England and the Mid-Atlantic would fracture, with both sides looking out for themselves, and not for each other's best interests. The Mid-Atlantic wouldn't take kindly to being called 'New England,' as that would make them feel like they have no cultural identity of their own. New England would feel insignificant and ignored, as the economic, demographic, and political centres of the commonwealth bearing its name would be located outside of New England.
You mentioned me by name in the OP, probably because you wanted me to see this. Well, I'm giving you the lay of the land as it's stood for literally centuries, before Colorado and the rest were even territories, and you're dismissing it as getting butterflied away, while more ephemeral differences, such as between Colorado and Kansas, remain cemented. It doesn't make any sense.
Also, and I don't know why I didn't think of this sooner, they tried combining the precise area into a single polity before in OTL. The Dominion of New England existed for all of three years before it tore itself apart because people from the constituent parts couldn't get along. Throughout colonial history, there have been points where the New England colonies have been willing to go to war with New York and Pennsylvania, most recently during the 1780s. When you have two parts of a single commonwealth that are willing to go to war with one another, or have a history of doing so, you've got yourself a recipe for disaster.
