If the USA doesn't federalize post-revolution, you could not only keep all the claims mentioned (West Virginia, Kentucky, Ohio River Valley claims) with the methods mentioned (better representation for trans-Appalachians, Virginian colonists moving westward and staying in a Greater Virginia), but this could possibly apply to Maryland as well in becoming part of said Greater Virginia. It wouldn't enjoy being part of Virginia 100%... but its choices are that, a Mid-Atlantic Union (which would tilt to abolitionism and industry in a time when Maryland is still heavily plantation slavery-dependent) or going alone (which with its small size is not very viable in the long run).
Think of it: OTL Virginia, West Virginia, Maryland, Kentucky, and the lowermost third of Ohio, southern Indiana, and Illinois's Little Egypt. There would be sectional tensions between the Tidewater West Country English descendants and their plantation slavery economics, and the North England/Scotch-Irish settlers in the Appalachians and beyond with their small freeholds, but overall it could be managed with proper representation and military power.
