The Orion Nebula

I'm trying to make a mod where the difference between beam attack and defense modifiers are much lower, but changing computers won't do much good if I can't reduce the bonuses on battle scanners, inertial stabilizers/nullifiers, or related systems. The point-defense, continuous, and autofire beam modifications and crew experience modifiers would be nice to change too, but since they're probably in unrelated parts of the code, I'm not going to hold my breath.
