Temple Sequencing and Possible Loop Question

Can I place the lower Golem works that is connected to the road, and then lock that room, plus the Smithy above to remove the other Golem works that is connected to the road and leave the last two rooms in place? I currently have all of the circled rooms except for that lower Golem Works in place in my temple.

For those that have experience with looping (if the above doesn't work), will the loop created in the first image above only mess up those 5 rooms and leave the rest of the temple unaffected?

One more question. If I instead let the 4 existing rooms destabilize and start again with a golem works to the right of that road piece, can I do the sequence shown in the second image (place a golem works in the circled square) to create the chain shown in the third image? I know I would lock the freshly placed Golem Works and the Smithy to the top right of it to get this result if I am allowed to place the Golem Works (Sulo doesn't let you but I've seen people say it should be possible).
