+1 to this.
Though I think the combat modifiers should be based on actual time the crew has been in combat together (at least for combat related things). This would make player both want to fight and protect the crew. Maybe a boost to PvP experience for crew as well as not solely encourage PvE farming and just running from PvP. Maybe would add an element of risk to being able to get a really top notch crew, while also encouraging risk.
