I just found this mod http://anvilbay.ru/files/DesertAlikr/while browsing around. It seems to recreate a part of hammerfell.

It's in russian, but the screenshots look promising.

Yes, it does! The readme contains an English html file, but the text is still in russian. If I get a chance I'll download it. I'm curious to see if it's in a different worldspace or if it's in Tamriel as part of the TWMP series.
