Everyone says Eta can't be removed...how about we do the next best thing? BLOCK ALL ACCESS TO IT. In the days before the release of the mod version which will close Eta, post a server message telling all ships to leave Eta by whatever date the mod version will be released. Then, completely block the jump holes into Eta by putting an impenetrable minefield around the jump holes. The minefields don't have to be big. The mines just have to be close enough together to prevent ships from squeezing through the gaps between the mines.
If I'm not mistaken, this would require much less work and still effectively remove Eta from any RP interactions, bringing the fights back into the Sigmas.
