About personality overrides, they work on AI ships? Cores also count as officers. If not, I hope what you will add options to make it override officer personality, I think its good to make two options actually, one for human officers and second for AI Cores.
Also another idea, is make personality override hullmod partially affect officers, I mean if you add to steady officer reckless hullmod he become aggressive, but not reckless, same with other officer types, if you add steady or timid hullmod to reckless officer he become aggressive, but not steady or timid.
