If smugglers are expected to role play more the complications of using a large transport for their profession (which even the Borderworlds Transport is,) then more support should be given them. Presumably if a smuggler ship is too large to unload on a planet they would go to a nearby station where they have contacts, like Rochester which is near Manhattan. There they would sell their goods and leave it to the Junkers to get them to planet-side dealers.
I would support the idea of hacking docking collars/mooring fixtures if:
1) viable drop off points (unlawful bases) with slightly less profit were made available at all of the major house planets. This gives the smuggler a choice to risk a landing on a planet when law enforcement is asleep, with a backup plan to land somewhere else for slightly less money.
2) These drop off points are run by a variety of unlawful factions. For example if I don't like dealing with Junkers I would like to sell to Xenos in Liberty instead, or Gaians in Bretonia instead of Junkers, or Farmers Alliance in Kusari instead of Hogosha. In other words don't assume all smuggling runs back to Corsairs or Outcasts, take the synthetic Marijuana runners into account and give them viable ways to role play their trade in multiple systems. LPI shouldn't be the only ones having fun with smugglers after all.
