Yup.
Though I doubt it would be difficult to implement all those aspects into the game.
Look at Mass Effect for example.
Adding a mode for combat simulations ala BC wouldn't be a problem since they already have a working model from that game alone.
Update/optimize the code, upgrade the graphics, and voila.
I mean, TNG: A final unity implemented various modes to the game.
Mostly it was all done via point and clicking, but if you'd be using the keyboard and mouse anyway for orientation and firing off commands, then it's not a problem.
A truly massive undertaking would for example be a Birth of the Federation style game that lets you create your own 'empire', zoom into the galactic map, assume control of ships, set up away missions, RPG elements to the game.
It would be almost like MMORPG, only in single player, but still massive.
