One thing about gold AP frankens, is the weight. The watch is supposed to look, AND feel hefty on the wrist. Its true that its something nobody can tell on the wrist, but if you have held the gen, you will know the vast difference, and that makes it a watch which you cannot reliably handover to anyone to appreciate, without being called out on the weight. My point is not to discourage you, but rather, inform you that I have done lead lining/filling mods before for a gold franken to make the weight close to gen spec. Not 100%, but enough for it not to be a tell when holding it in one hand and the gen in the other. This is something you may wish to consider.
Remember that no franken is perfect, you need to manage your expectations. The best AP franken builds that I have seen here have tells that it isn't gen, some significant, some subtle, but NO franken in this hobby is without flaws of one kind or another. So understand that you will be spending, say $6000 to get a watch which will look impressive no doubt, and in your case, a model which looks fabulous. But the imperfections will catch up with one day when you know where to look. An example of a top-tiered franken IMHO is the RGRC Jurgenk posted. That watch can practically be posted on instagram and anywhere without anyone calling it out. I kid you not. But a watch, AP in particular, is as much about the feel as the looks, and this is the part which bugs me personally. For example, I cannot abide the non-instant date change in the LWO283 (peeve of mine, and not important functionally lol) and other things like alignment between parts, and geometry of case etc. I have no doubt that you will own an impressive looking watch by the time you are done, particularly for this model. If you are pleased and happy, that matters more than any opinion in the world. I will encourage you to go ahead with the build and seek help when you can from the experts here.
