It IS possible to make the ship more effective; Move the reactors near the parts that need energy (Thruster don't need much energy, so move only a reactor towards a load of them) to make them react faster to energy usage start/fluctuations(for shield)(don't forget door management to make plasma battery delivery quicker 馃槢), Make unused corridors that looks like empty spaces either structure/armor, move the crew beds toward the center, (or towards the place that needs many crews upon battle) but try to move to less decal-focused areas because it won't wreck the decoration as much. All i can think right now.
