They should just open up DM's to freighters and other transports. They would be considered far more valuable and useful if ships could actually RP with them instead of only saving them as carrier bays for combat snubs. Perhaps allow docking of ships with 3600 cargo holds or less. People would actually get use out of acting as a mobile docking station for regular ships going about their business. All sorts of uses for miners/scrappers having a ship like that around would pop up. Not to mention, it alters the value of your tactics, needing to concentrate on carrier ships first, if attacking or pirating. However if this were done, the value would have to go up for sure, and perhaps limit to 1 bay per transport.
