Further, I would argue that the SW FTL travel method is different from the ST FTL travel method - I think the SW FTL method precludes exchanges of fire.
While the ST FTL method (as demonstrated by your statements) allows it.
Granted, I think it would be quite hard for the Imperial forces to hit a Fed ship while it was in warp, if for no other reason than the speed of the target.
But it would still seem possible., as you mention below.
Either with insane numbers of guns rapidly firing TL and other bolts, or with guided missile weaponry. Or both.
