I've seen this before in other games, and it shouldn't be something that difficult to program, 'Saved Ship States' where you click a button or two and you swap out your whole ship.

For example I switch between having +1000 Cloaking most of the time, but when I go NPC Hunting I switch off my Cloaking and put in my Defenses. What if all this could be automated with a single click?

And it'd work for Energy swapping for leveling up too! About to level up? Just click a 'Ship State' and it unequips all your relays in one go!

This has been suggested before as a ship template.
