When using mobs that normally spawn with weapons as custom crew are unarmed and never spawn with armour.
Can these mobs at least be made to spawn with their usual weapons (Bows for Skeletons, Swords for Wither Skeletons, Axes for Piglin Brutes, etc.)?
Alternatively, could you add configurable custom equipment and/or equipment pools for custom crew types?
This could also tie in well with #47
