Just a small one, that would probably eat too much time for relatively minor payoff, and largely came about because at one point I ended up with seventeen officers (!).
I propose that Officers can get injured or killed. For instance, if their ship blows up, have a chance for them to actually die or be unuseable for a month or two due to injuries. This would cause players to think about how they use their officers from battle to battle, and have a reason to have extra officers on the bench to step up in case an existing officer dies or becomes injured. Right now, officers are a resource that once you get them and train them up, you don't really need to worry about losing them or worrying about getting extra back ups. Having a more dynamic rotation of officers in the fleet however could be more interesting, and make having high level officers seem more impactful as they'd be more difficult to accumulate.
Mind, this suggestion came from the fact that officers were a lot more common than they ought to be when salvaging derelicts. So a possible solution would be to make Officers appear less commonly as a find in derelict ships.
