Doom originally tried that, with Tom Hall doing a lot of design. Then they figured out that it sucked, and decided to go with more abstract playspaces instead.

Even in Half-Life 2 and things the current industry practice is to "box in" the playspaces to get the flow correct and then skin them to look like actual locations. If you want a game with some actual attempts at realistic spaceships look at System Shock 1/2 or Dead Space. Even in those cases it's pretty clear that they have taken great liberties with what would make sense.
