The Centauri Mass drivers are a sort of slot mounted on the front of their cruiseds with a roughly round asteroid guided towards the planet with what looks like a type of railgun. Assuming they use railguns to accelerate the Asteroids, I don't see any reason why they wouldn't work in hyperspace, being that B5 energy weapons work just fine. Now, You have a good point that only the Minbari or an elder race would have the capacity (i.e. amazingly accurate hyperdrives) to target an area as small as an ISD in realspace, BUT the Drakh or the Shadows could do so, and the Centauri have been known to ally with such powers. In my story, maybe they will. I will also assume that ISDs put out an incredible amount of power by B5 standards and that detecting them, even from Hyperspace will be amazingly easy. What with those giant engines and such, the Imperials have never been accused of being subtle.
Now on to the second question: Assuming they could get the ISD to hold still (Give it something to shoot at) do you think they could gather enough ships in one place to launch enough asteroids that they could even damage an ISD?
Third point: There is an argument that the ISD was either not damaged by the asteroid, it just seemed like it, or that it was damaged off screen by hundreds of other asteroids.
That may very well be true. If this is accurate, then the whole maneuver, even if it COULD be pulled off, would be ineffective, because the ISD's shields would need to be hit by hundreds of asteroids at once, and the Centauri fleet only was shown to have a few dozen asteroid spitters.
Thanks for this actually, this is shaping up to be a GREAT (if futile) Dambusters type dramatic scene later on in the story!
