There was actually some serious discussions between Alley and the once active and official PLR Rogue Guard faction on this subject given that Cassini, the Rogue guard system is scheduled for deletion once the guard systems all go poof. Some of the assets from Cassini, the important and viable stations and such as well as part of the nebula were going to be moved into Galileo. It's "Reconstruction" would be explained as Orbital drift, (or whatever the term is for when a solar system moves after years and years into another systems area) This idea could in fact be used as the base for all other system changes should a system be removed that is relatively close to another that is staying.
Not sure if this is something that could work for what you are asking, but it's something that I know makes a fair bit of sense.
