I'll repeat what Dab and Seth have said here. Bases aren't made as models; they're made of multiple models all stuck in space and positioned so they look like they're all one big thing. The models are then "linked" to the main base so it selects the base when you click on them. It's done, as Dab mentioned, mostly in FLE, as doing it in the INI files'd take a ridiculous amount of time. As I already have your Skype anyways, poke me some time and I'll walk you through it.
But as for changing Lividia, that's Dab's system, so no messing with it. In general, you don't mess with systems modded by other people unless the owner of aforementioned system asks you to. Omicron-74 no longer has an owner, but Dab's old faction originally owned it. It remains his.
