Again: what's the point of equipping guns, if it's better not to fire them most of the time? You are just crippling it more, than helping. Though I personally would have gotten 2 flaks instead of flux distributor. It's not a big difference, either way, since an Atlas Mk II that's being shot at is a dead one in either case.
If you want to know what other ships can get by without equipping many mounts, that would be Paragon (though it's more for flagship ones, rather than AI), Conquest (if you don't go for asymmetry), Legion, Apogee (you don't really need those smalls), Aurora (if you don't want to go full missile), Dominator (same as Legion and Apogee, save for rear smalls), Tempest (does undergunning count?), Omen, Scarab, Monitor and, finally, borderline every carrier.
