I know its his design, but I don't think it makes much sense, aesthetically, that layout. Having the CO seperated from guests would make things uncomfortable. Imagine, you're an admiral who is aboard during a mission, you'd have to have the CO turn around to talk to you - taking his eyes off crucial data. I would say pull out the current CO seat and make the center guest seat the CO seat. Putting up railings behind the helm-pit would give the CO a good thing to lean on if he stood up - nice authoritative pose to anyone on the viewscreen.
