Hi Scott,
I hope to be sailing this year - all things being equal within a month - but have spent two years rebuilding the Maxi 95. I have used professional help twice - once at the beginning, when I was doing not quite as much ripping out as you but still a fair bit, and again in the last few weeks, when I just needed some help to epoxy coat the bottom, paint decks etc, while I was sorting out steering and motor and bits and pieces - all of which has taken far longer than I expected.
I have no regrets, but it has not all been smooth sailing. I like and trust the guy who is working on the boat, but at the end of the day, he has not done 'his' parts of the rebuild exactly as I would have done and although there is nothing that is likely to keep me awake when I am sailing, there are parts of his work that will nag at me over time.
On the other hand, I still have my job, my children know who I am and my partner is more supportive of the project than would have been the case if I had allowed it to take too long, or been more obsessive about it than I already am. I generally work on the boat every night and put in eight or so hours at the weekend.
Like you, I am basically happy that I went for a total rebuild rather than conversion, repair and splash. Like you, I now feel that there is not a single part of the boat that I do not know intimately and this helps my general anxiety about things breaking, as in at least I will know how it was put together when it breaks and will hopefully have some idea of how to fix it. Was it a sensible move, to echo a discussion on another forum? Probably not, but I have enjoyed the process a lot!
I would say, though, that you are approaching the question from the wrong end - your first problem is to find a person you can work with and who is open to thinking outside the box. If you can find that person, then go for it, and enjoy a beer at the weekend!
