How's this?
Downsides: missiles have less range due to being moved to the back, tractor beams may be in a slightly awkward place, impact to sustained operation, and FTL jumps are more expensive.
Upsides: factories moved closer to what they need to supply, less chain reactions blowing it up, 60% more cannons, control room moved out of the blast radius of the reactors, front is more armored, and it's faster.
Sides: PD replace by flak.
