Hmmmm... I like to at least try to stick close to the sources, if possible.
Two "Heavy Lasers" might be 50 ton laser bay weapons (from my house rules
here). 57 missiles, divided by 3 missiles per turret, gives us 19 missile turrets. Adding in the "spinal laser" as a big bay weapon (maybe a 500 ton bay?) gives us the use of 49 of the 50 potential hardpoints, assuming a 5000 dton hull. If she's a smaller ship IYTU, just change the "laser bays" to regular laser turrets (and the "spinal laser" to a 50 ton plasma/fusion bay?) and you need only 32 hardpoints.
That might work....
