Take a THICC container and turn it into a combination of quarters/workstations for 6-10 crew. Something like you'll see on construction sites where containers are converted to several types of facilities like offices or storages.
This would have 2 effects:
- You can take up to [max] extra crew per container on your dives. This would help ships like the Bender which don't have enough crew space or serve as a tool to take you extra crew for on the job training.
- Taking less than [max] crew would help alleviate crew unhapiness in cramped ships because they would have more space to available to move around.
Plus it would be funny turning a Titan into a space bus and tour around the rings 😄 .
Here's another (related) idea: Groups of people in Enceladus paying for tours to the rings. The would request that you reach a certan depth or visit some POI and offer an amount of E$ depending on those conditions. Some thrill-seekers might even ask you to engage in a fight with a pirate. You could even have different tiers of the module with varying degrees of luxury and charge accordingly. This would also serve as an alternative source of income if mining is not doing it for you or you just want to take a break.
(If this sounds old to you is because it is. Elite Dangerous has had passenger cabins for decades since 2016.)
