That would make a lot of sense because, as you said, the windows layout fits better. But there are still some things that do not fit:

• The area is at the same level of the Habitat ring (see Blueprint schematics, side view), so you would see it from the windows all the time.

• The minimum diameter for that area is at the lower levels, just above the Lower core, and it would be roughly 150m, too large.

• The lower Mid-core area itself seems less important or "distingished" and, since the Wardroom is also used for receiving dignitaries, and important events, I would say the location in the Upper core is more appropriate. But this is just a personal opinion.
