This'll probably be the last update I make for about a week. I have an out-of-town work conference, and I've got some major coding that I have to work out to see if MVAM with three pieces is even a possibility in Sins of a Solar Empire. Recombining two halves of a vessel wasn't something even conceived of for the game and, for a long time, was thought to be impossible. But, I was able to figure that out with a fairly elegant (if complex) solution, so I'm hopeful I can do the same thing with three pieces. The result of that work will determine whether I go with two or three separate vessels here. If I'm successful, my current plan is for the third ship to be a small fighter-type vessel that makes up or detatches from the front tip of the lower saucer rim where the yacht currently sits.
In the meantime, here are some images with all of the appropriate seams welded so you have a better idea of the final version of the ship. I've also replaced phaser strips on the sections that have been reconstructed, and all the impulse engines are "finalized"... for now, at least.
