To do that, they would have to include a new NPC system, but I can't see that happening for a minor update with limited resources (the rest of the team working on 4.0). They have already mentioned a minimum member requirement. I don't expect that to change at the moment.
Now if we get some small personal carriers (2-3 small-medium ships) at a later date which have nothing to do with squadrons, then yes I would also like to see an NPC crew added for that.
Honestly speaking, I think the foundations for all those NPC things are already in the game.
NPC crew -
Telepresence is already there in MC. Ditto Crew Lounge.
That means they can simply put a cosmetic requirement for larger ships to go to the crew lounge of the starport and hire a Crew just as a prerequisite to fly the ship.
It's not a big deal.
So that second crew member goes into your co-pilot seat. He or she essentially does nothing except to act as a bloody wallflower.
Or... since you have two Holo-Me characters.... just assign one as your main pilot, and the other as your fill-the-seat lackey.
For the larger three-seater ships, I assume those are the ones with Fighter bays? Put your hired SLF pilot there.
NPC Mercenaries / Wings -
The mechanics for SLF and giving orders are already there. Plus, NPC wings already exist. So obviously the code for ships to follow a leader, as well as take commands, are well established in the game.
NPC Squadron Mates -
Again, just an extension of the above. They just need the squadron to be persistent.
This means that if you give an order for the squad mate to go source for something in the system (like mining a ring), he goes out and does it, and you can see him in-system all of the time. And not in a way that he disappears out of your instance... and magically comes back 30 mins later with the mats you ordered. That's a cheap way out.
If this can happen, then perhaps SOLO/Lone wolf player owned Carriers makes sense.
