I've been toying with either the RT being a played by the group as a whole. (Sort of troupe play.) The group as a whole selects who plays him in combat or handles speaking for him. The other option is that the PCs are investors in some fashion. Maybe the missionary brought in 80% of the crew, and they are more loyal to him than the RT. The tech priest commands the tech priests, and lay workers. The Navigator might represent his house's shares in the ship. (money, equipment...) That way the RT must listen to the rest of the PCs, and coldd even be out voted on a given matter.
That seems like a wise arrangment. Giving the other players some political cache aboard the ship would solve the problem nicely.
An Ad Mech member would wield almost automatic political athority for the same reason their order does. If they don't do their thing, technology ceases to functioon.
The priest could have been the primary motive force in aquiring the funds and the warrant for the expidition. This would lead to the classic and entertaining 'meddlesome priest.'
The Void Master could be such a respected and high-ranking old 'Salt Dog' amongst the crew of the vessel that he could easily incite a mutiny if he were so inclined. He also knows more about direct command of the rank and file than the Rogue trader does, and his counsel would be invaluable.
Navigators would wield athority over the RT for similar reasons the Ad Mech does.
The Arch Militant probably commands the military brach of the fleet and therefore would be a dangerous companion to alienate.
I think a balancing act like this would serve admirably as a curb on the RT's power should one find one has no player up to the challange of the role. After all, the RT enforces his athority through force of personality, not necesarily by fiat (like inquisitors do).
