I think that would be very cool. It'd be nice to equip them all with custom built weapons from the smith. But I feel this is likely something that won't happen for a while. There's a million and one things to do first. Maybe a Modder could work on this? Create some base troops with stats but no equipment that you could give equipment too. A bit like companions, or the free company from the [mod I can't remember the name of] in Warband
