This mod erases Solstheim from the map, S'Virr from Khuul and the latest rumors pertaining to Solstheim from the accessible dialoge. In short: all objects and resources that Bloodmoon adds remain available for other mods to use, but all accessible in-game references have been removed.

For all intents and purposes, the Sea of Ghosts is in the state it was in the Arena and Daggerfall maps - Solstheim free.

Hircine will have to run his Bloodmoon game with the Companions this time.

Pretty much a resource if you want to place something in Solstheim's place or extend the coastline of Tamriel Rebuilt's landmass to the north as it is in the Anthology map.

I use it as a basis for http://www.gamesas.com/topic/1513231-wipzrelz-anthology-solstheim-albeit-it-does-move/ and thought I'd release it as a pars pro toto as well.

Um. why nix Solstheim> Why not just, I don't know, not install Bloodmoon?

And then what would you do with mods that need Bloodmoon.esm up and running?

My guess is that this mods allows you to keep the Bloodmoon objects (models, scripts, variables) but eliminates all references ingame. That way, you could still have Bloodmonn.esm registered but no trace of Solstheim.

Edited op for clarity (Kalon is exactly right in what it does). It does leave the interior cells alone, so theoretically you could run this thing with http://mw.modhistory.com/download-33-7149 or something of equally dubious choice.
