No its not really feasible without a pod long before independence or sometime after. Until they replaced the Articles of Confederation with the Constitution the USA government was more comparable to the League of Nations than most other political organizations; No federal courts, no body to enforce laws, no universal currency, no taxation, no trade regulation, and laws passed by Congress were merely suggestions to the states. Oh, and because there wasn't a head of state, foreign diplomats were expected to negotiate with representatives from every state for any issue. These are symptomatic of the fact that individuals did not identify themselves as "Americans", but as New Yorkers or Virginians, and didn't want Virginian interest's influencIng laws that would effect New Yorkers and vice versa. American started to become to primary identity after the Civil war I believe. My understanding is that "State" was equivalent to "Country" and not "province" back then. Any talk of centralizing the country would turn to talking about Britain and all the reasons for independence in the first place kinda like how Godwin's law works.
You could have a country in the same area that speaks English and has many parallels and many of the same place names as Otl eastern USA, but you would have to butterfly the revolutionary war, federalist vs antifederalists, and probably even the "United States" part, because it would require Americans of that time to see government as a positive rather than a hindrance, and frankly I think that's herding cats. Hell, the antifederalists thought the US constitution was TOO much centralization, and that wasnt an unpopular opinion.
I think you can make a more centralised entity in place of the USA that eventually gets independence from Britain, and I think you could have the US centralize more after independance in increments that could be exponentially more radical the farther in the past the revolution, federalism debate, and Articles are, but in the era where the federalist and antifederalist debate is ongoing, a full on centralist would be only slightly more popular than a monarchist.
