That would be so OP idk where to start.I'd like to see the ability to install more than one fighter hangar and have a full 3 NPC crew as well.
(an elite NPC is already a floating constant damage hardpoint)
You can already have two of your friends out in SLFs, or one friend SLF, one friend gunner, +one NPC etc, so adding more could imbalance everything.
(two extra pips from friends on board is already a massive boost too)
The big three being able to finally field a sidewinder as per the lore howeverrr....
