Potential future cargo grid ship modules

I was wondering how customisable our ships will be in the future (ouside of modular ship variants) and if we'll be able to buy add-on modules for them to add additional functionality. I did some rough renders for fun of a couple of potential modules that could snap to the cargo grid of any ship. These are just for illustrative purposes, not for proposed looks.

These are seats for passenger or dropship functionality (with weapon holders) and storage cupboards for armour, Picos or whatever you wish. Each module takes up a 1SCU cargo slot and fixes securely using the cargo grid box holding tech. Looking at the Cutlass Steel, it looks like you can fit two seats to each 1SCU space.

Other potential modules could be beds, bathroom (with sealed tanks) for the Cutlass Black, scientific equipment, weapon racks. kitchen equipment, tables for crew to eat/chill at or medical equipment. Some may need power from the ship, so could affect other systems. What would you add?
