I was thinking in a similar way Cam, but making the faction cap weapons stronger/weaker to certain sheildtypes like their fighter weps.
Like bretonia is particle type, Kusari photon (?), IMG tachyon, etc etc.. instead of the normal energy type that has the same damage to all types of sheilds thing we have currently.. I beleive it'll put a lot more depth into future cap battles than it is now.
Problem is, what would you classify basic turrets as then... Laser?
