Sophie's Revenge - The Conundrum in the Captain's Cabin

I definitely like to think somethings all the way through before I start cutting things up. As I have mentioned previously I'm starting the rebuild of Sophie's Revenge with the Captain's Cabin. Ultimately I'm envisioning this as being broken up into two compartments; the Captain's Cabin itself and officer's quarters (or what ever the pirate equivalent would be). I need to add quite a bit of detail in both areas which has brought up a couple of things.

1) The ceiling on the Captain's cabin. I'm going to go higher than I originally intended which will increase the overall height of the poop deck and the map room. This deck will probably get shortened because of that, but it will solve the "skylight" problem. 

2) The Captain's cabin should be pretty extravagant (its a fantasy pirate ship after all), while I can work with it as is, I could take it apart. I stopped short of complete disassembly but the reality is that this section is really five pieces, of which the Captain's Cabin is three of those. It won't be easy to separate these pieces, they are glued together very well.

So just some more decisions to make and decisions are easier to make if there are pictures!

First order of business. Make this into a single deck. It has to support the cabin and the mizzen mast in addition to the Captain's Cabin and officers' quarters.

Should I or shouldn't I? The Captain's cabin can be broken into five pieces. The circles show where the seams are. These are well glued together, I'm not even sure it will be possible to disassemble them, it might take some knife work although this plastic cuts pretty easy.

As it stands. This is how much of the ceiling of the Captain's Cabin would be shortened by just extending the existing quarterdeck back to the stern.

This is a look at where the deck I was originally planning to use would intersect with the Captain's Cabin. I would still be losing a good portion of the existing windows, hence why I was thinking of some kind of "skylight"

If I increase the height of the poop deck, the gap is going to be really large. That, in turn, would lengthen the run of stairs on either side, which I could compensate for by reducing the length of the poop deck. However, that would impinge on the ceiling below and require stairs to get to the map room.

Lot's to think about before I start building things. Although I could just start with the Captain's Cabin and finish it out and build everything else around it. Some seat of the pants work for sure.
