The problem with implementing this idea of boarding stations is the fact that you have to devote a lot of resources into stations themselves. Developing a concept of the station, mapping it out, modeling it, creating the art assets, play testing it, then revising it to the final product. That takes a lot of time.

But if we have to use CURRENT assets to mimic the station, then the Gallente Research Facility is the closest one we got to that kind of environment. Unfortunately you have to remodel it to close off certain areas to simulate a closed environment. Not only that, not everyone enjoys that map. There is a reason why we call it the Gallente 'Lag' Facility in the first place.

The preferred alternative, and perhaps the most practical one is something that is inspired by the recently introduced MCC Construction Facility which is nothing more than a collection of CURRENT assets such as small and medium sockets mashed together to create a new facility. This proof of concept developed by CCP shows that it is possible to use current assets to recreate a variety of conditions and possibly even simulate a station environment.

But as for adapting the idea, I would say that it's best to tie in the station environment to the Customs Office in FW space. For those of you players who don't know, Eve Online players have to access the resources of their planets via a single Customs Office that is assigned to each planet it orbits and there is only one such office per planet. The Customs Office is also player owned and is the source of the owner's revenue in terms of import/export taxes.

And since planets are the only source of materials needed for the construction of control towers, some of the fuel, and even the Customs Offices themselves, this could change meta across both games.

This is why I recommended Customs Offices as a medium for the link. It's not part of any sovereignty mechanic and it allows station-like environments to be feasible outside of null-sec space because player-owned Customs Offices are everywhere in all three levels of security. This could also help strengthen the connection through FW.
