Skyrim and Elsweyr are at opposite ends of the continent.
Since when does this matter? In morrowind you had to take a boat to Tribunal (the name of the island escapes me). iirc you couldn't get there if you just levitated from the main part of the game.
It wouldn't be the first time they made you use a portal, but I'd like morrowind more simply because of the boarded-up exit of Riften.
Though as others have said Morrowind, if re-done, should be a whole game. It wouldn't make much sense to me to rebuild it in its current state, since not only would the landscape be very different, but the Interface is vastly different from Morrowind's as well. It's not like I can go up to someone and ask them for a little secret or a little advice, or information on their race... etc.
Ultimately I'd love both an expansion and a remake of the game but if one is done I don't think the other will be... So I really don't know.
