The AI should have a more useless upload, and no turrets.
Maybe just more walls for defense but turrets are overkill.
As long as the upload and AI are in different regions of the ship it would be good.
Like maybe AI is the very center of the station(as it is usualy very easy to kill anyway, this would make it tougher) and the engine the very back, more designed like a ship, some of the engine's power goes to propulsion systems that can be used to keep orbit, a useless feature but maybe if the orbit isn't kept we could have some neat side effects, and possibly new jobs such as pilots?
Scientist and chemist should be mixed into one. the testing chamber can be altered to have a grenade testing device the lobs the grenade into the chamber for testing and such, liquid cannons for deploying thermite to a test wall (these would be non moving items like the cryopod) and such.
My 2cents.
Or replace that AI being in the center with the bridge and access to AI upload in the bridge, the AI somewhere elss. like near the engine. Maybe have those who start late begin on a "planet" where then they start nude and have to get a suit on and all, then have a computer terminal that has all open job spots on the station and at the end a teleporter to the station, they could also go outside onto the planet where they can look into the green grass and trees at the atmosphere which is like a forcefield where they cannot pass off as a person.
Maybe some wild monkeys could inhabit the small planet. Anyone have the problem when they type too much on this forum it does this freaky bouncing where it goes to the middle when you type and flash down to the are you are typing when you type a letter? That would explain my spelling and grammar errors.
