Are you intending this door to be a display/novelty, or do you intend that it provide solid security to a home-made vault? In either case it is heavy enough you’ll want a darned strong, well-braced chunk of concrete for mounting the frame, especially if you intend to swing it open and closed. Hiring an engineer sounds like a good idea.
The simple way to disable the time locks is to never wind any of them. Assuming the two outer glass doors can be locked, keep them locked. A more thorough way might be to remove part of the linkage between the door and the lock. I’m sure others here will have suggestions as well. The time lock is not original, it is a contemporary replacement from Diebold; the original is missing, probably replaced because it could no longer be serviced. Assume that somebody will figure out a way to lock it, or at least the pressure system, and if it’s just for display be sure it is not the only way out of a room. Talk to your insurance agent.
Round doors have had quite a bit of discussion on antique-locks over many years. Your door appears to be a York, of a style I call a “cam plate” mechanism, possibly the most common in the US. I don’t believe there is a common name for the mechanism and I call it that simply to distinguish it from other mechanisms. You could try a search on antique-locks for “round door” and/or “round-door” (without the quotes), and narrow the search at first by using Advanced Search and check the Titles Only box.
