It would be a nice-to-have, and nothing more. The thing with such gimmicks is that people look at them, explore them for a few hours at max and then are done with it. They will miss it when it is gone, for nostalgic reasons. To be honest, it is not worth the effort. If you learn how to model and do all the stuff necessary to get things in to the game, it would be more helpful to have that talent used on completing ship lines, creating more station parts or asteroid models we could use.
Nice idea, would be cool, is very unlikely to ever happen. Project size too large, and doing things for Freelancer is pretty tough. You need a very specific set of tools and months of training to learn the correct methods and make things work in the game without bugs.
