I may be wrong, but I was thinking the Machinarium with 8 gear rooms was the solution to something, and was being vague about it. So Workshop, Security, Utility Closet, Laboratory, Pump Room, Boiler Room, Hall of Mirrors to duplicate one of the above then Machinarium.

As for the drafting studio, that might be a solution. I’ve had bad luck getting it to pull too, only having seen it twice. Been holding off on picking an outer room in recent runs so that if I see the drafting studio again I can burn rerolls to force a shrine to get maximum use out of it.
