I would think you would leave the tackle in place until construction was completed! What if the rudder drops onto a shipyard worker or similar? The liability suit may well stall the build progress for quite sometime with investigations to be completed and appealed etc.
The level of research you have put into this is simply amazing. I would even suggest your build log would be worthy of publishing as a book once you are done. That is assuming you ever get there, how many years has it been so far? HAHA
As far as moving aboard goes, I would rather have an officers space, somewhere clean. And I will be sure to keep the minions, sailors and marines looking their sharpest for your display casing! My wage expectations are meager and are in line with current market expectations of an officer rank in HMS Victory's service.
