The following will probably require a massive amount of time and effort from the coding team, just a heads up.
First up, the shuttle will be made a lot smaller, chemistry will be either moved from medical to cargo or removed entirely, and cargo techs jobs will be requiring a lot more responsibility
with this, the way that the station gets its equipment will be changed, instead of having points to "buy" everything with, there will instead be giant machines(I'm thinking 3x5 tiles) which can produce most of what the shuttle would otherwise be taking from cent-comm, medical will no longer have the ability to just sit there and create grenade/bombs from pure energy like they have since forever, instead, they will now be forced to work with what they have until mining can do their job and bring in a new and much wider range of ores from the mines(insert lots of raw elements, like a lot) that they can then put in the redemption machine, which will then go into the really big machines to produce the raw chemicals the chemists(if they are still existing) will use to make medicine that will be delivered to med-bay.
now as for the cargo techs, the machines will be their job, overlooking the stats of the machines, managing coolant, and shutting them down if needed to prevent sudden releases of super hot gas, radiation, and straight up explosions, and replacing the specific parts(much like Borgs have) that eventually will break down in the machine, meaning maintenance will be constantly needed and cargo techs wont just be sitting around bored.
The shuttle will still be in for the things that cant be produced by the machines, such as animals or emergency riot equipment, but other than that, its up to mining and the cargo techs to be sure that the station gets what it needs.
