I don't know - I mean you could, it depends on the GM, but the manufacturing of engineered products and biochemical processing seems like extremely different beasts - its hard to imagine they use any of the same machinery, personnel or set up. You can make a better argument about the Reclamation & Medicae Decks. Librarium & Laboratorum doesn't make any sense to me.
I could believe a homebrewed heavy frigate built around a Manufactorum similar to how we have transports built around Main Holds and carriers built around Flight Decks, but it'd probably be something you'd have to be on good terms with the Mechanicum to get your hands on.
Personally I think the way achievement points is listed is idiotic, so I can't really comment on that.
