So, the most recent variant of this Ship Component now reads:

Archeotech Component - Bridge of the Eternal Vigil
This ancient bridge design, which borrows from that of the most powerful land-based war machines, the Titans, is viewed by many with more fear than awe, as the very idea that the ship's Lord-Captain would be permanently interred, never to again leave his command throne, is terrifying to consider. Only the largest, most powerful ships are likely to receive this upgrade, and only if an individual willing to be forever merged within their ship can be found. To the willing recipient, radical procedures are performed, removing many of their internal organs, and replacing them with powerful cybernetic devices, which will be able to carry them on through the centuries. They are permanently anchored into place, becoming immobile, but their connections to the ship allow them to perceive, and to manipulate almost any system from the bridge, as if the vessel, itself, was an extension of the Lord-Captain's body and senses.
Man in the Machine: The ship's Lord-Captain, who has been integrated into the bridge, gains Machine (4), though this trait does not affect the recipient's mind, in this case. Their Movement permanently becomes 0. They also gain 1d10 Insanity points, due to the initial broadening of their senses, and an additional 1 Insanity point each time the ship sustains a critical hit (a Difficult (-10) Willpower Test can negate this, as the Captain has become more fortified by his condition).
The Walls Have Eyes: The Lord-Captain's insertion into the ship's systems gives him unprecedented observation and interaction with his crew. While this can make for a much more smoothly running vessel, it can also grate on the crew, who quickly learn that there is no place on the ship, their home, where the Captain is not watching and listening to them. Permanently reduce Morale by 5 points. From now on, due to the speed at which the Captain can respond to any problem and give orders or inspiration to the crew, any crew or morale loss will be reduced by 1d5 points to a minimum of 0.
One With the Hull: The embedded Lord-Captain has senses, and control, over almost every inch of the vessel. When this ship is the victim of a Hit and Run action, he treats the opposed Command Test as a Routine (+20) Command Test, rather than the usual Ordinary (+10) difficulty.
One With the Weapons: His union of sensors, skill, and weapons grants the Lord-Captain's ship increased accuracy. All Ballistic Skill tests to fire the ship's weapons conducted by the Lord-Captain gain +5.

Hull: Cruisers and up | Power: 3 | Space: 1 | SP: 3
Hull: Battleships          | Power: 5 | Space: 3 | SP: 3 (apparently, Battleship's stuff is a lot bigger)

So, I rather like how that all works out, but is there anything else the Mechanicus might do to the Captain, to further aide him in his eternal vigil on the bridge? Might they give him the Logis Implant Talent, or a rare, GQ Cortex Implant? Any other cybernetics? Might he benefit from Prosanguine/Autosanguine? I'm not saying more is needed, but sometimes, people can go overboard, and I wonder what other boons the recipient might receive, for being anchored to his ship for all eternity. Any ideas would be nice.

I would say that the captain should automatically gain the pro/autosanguine talents as a result of the extensive cybernetic conversion and immersion in amniotic fluid..

On an interesting sidenote that did come up…The battleship i have that is fitted with it  also has the regenerative hull trait…The ship tests ( using the Captains Toughness trait ) to repair the damage so it can regenerate quite quickly ( same as regeneration trait ) instead of waiting longer to begin and taking longer to regain the points.
