With all these tweaks, I'm surprised you didn't add the Florida panhandle to Alabama.
I guess you're right, that would actually have made more sense. For aesthetic reasons I'd have to split it between Alabama and Georgia, and that would still leave us with enough population for two States. Though probably not so in the 1960s, when Florida as a whole was only an average sized State.
I was only thinking of the part west of the Chattahoochee and Apalachicola Rivers. (The Chattahoochee forms the southern half of the current Alabama-Georgia border.) If you move the Tallahassee area into another state, Georgia would make more sense than Alabama, but I see no pressing reason to make Georgia a bicoastal state.
