Non-combat NPCs: yes, at the moment. Of course their weapon skills will be terrible so they won't be that good. Whether at a later stage they will be restricted or not, I don't know. SO probably best not to base any tactics around being able to use them, at least in the long run.
I'd say either their hull needs to be looked at, or the way infantry weapons do damage to them as well. Droids typically have hull around 10 or so, less for the non-military ones. This is significantly less than any NPC if they are treated the same way for how damage is calculated.
