Nerfman,
The biggest problem with that (though I'd love to have missile pods too!) is that you can't actually use tractor beams to TOW things. All you can do is to push stuff around in tactical combat. If the tractors actually let you tow, you could create large sats full of CSMs and drag 'em around with battlecruisers and dreadnaughts, and do the Manties proud.
It would be cool... though I don't want to see salvos like some of the ones in the books where they popped multiple THOUSANDS of missiles in one shot! At least not from the receiving end...
