In the (non-Star Trek) novel series The Lost Fleet, captains speak maneuver orders and the ships execute those orders. We never get a mention of a helmsman nor manual navigation. That would be a more sensible system for Starfleet ships since the episodes tend to leave most maneuvering to the pilots without any orders short of saying, execute pattern XYZ.
If we have to have a helmsman I would just put him center, then flank him on either side with ops and tactical. There's room for it, and they make sense together as the most critical for the ship surviving in emergencies. Science is frequently important so Spock's position about 15 degrees forward from hard right makes great sense. Engineering could stand to be in the opposite position on the left.
The thing is, the high screens of TOS and of the rear consoles in TNG are extremely smart. Either I would put screens like those behind the three forward stations, or forward and above, which would require the main screen be raised up. Depending on the captain's position it might not be by much.
I would forgo steps and rails since they're dangerous and instead give the captain a pedestal seat so he can sea over everyone's heads.
TNG also has weird division of tasks. For some reason Worf deals with communications, and I think Paris in Voyager handled sensors which makes a little sense, but it makes more sense to me if ops handles communications and sensors. Or make communications fully automatic and as smart as the sliding doors. If the ship is hailed by a new ship, Picard could get a message interface in his arm rest, or where ever he is as long as he is on duty.
