I was thinking about a new Carrier Vessel Type Capital Ship (maybe alliance as it has none yet), A capital ship that is not combat oriented, but which allows you to dock on it, and then jumps to a distant star cluster, either for exporation or colonisation. Might come when the Alliance Colonisation initiative kicks off.
as capital ships have a huge jump range. Colony supply runs should be based on large government supervised ships, not some independent pilots jumping around systems for weeks. Also, roaming systems in capital ships for exploration is not practical when you can bring with you a squad of eager independent explorers to sweep the cluster.
The mechanic is already implemented with Jaques Station. all it needs is a Good Time Table For the jumps and the ship.
BTW, the ship could function like an outpost, with a bunch of landing pads outside situated on the Ventral and Dorsal sides of the hull. Primarily small + a few medium ones.
The more i think about it, this is the best mechanic i can think of in terms of usefulness, lore, balance and common sense.
