Y-wings appear to not need Bomb Loadout to carry bombs, so does it have separate slots, or ones that take a torpedo or a bomb.
Might ordinance boats get slots that are torp/missile. With the K-Wing, I can see going to 2 mixed slots because the second torpedo was almost always Extra Munitions.
And maybe some ships might allow for a slot for either a turret gunner or a regular crew, though I can see some being a gunner slot only.
All in all, something an app can easily manage.
