Don't forget that the bridge module tapers upward, which makes the outer edges have a lower elevation than the main bridge/dome area. The ready room is already at a lower elevation from the main bridge (about 3 feet lower) and I'd hesitate to drop it any lower than that- unless the captain just loves getting the exercise of climbing a full flight of stairs just to get to the bridge.
I'm willing to wait and see what Sean can come up with for a deckplan. Chances are very good that he'll knock all our socks off- I mean, when does he NOT?
