Something I was thinking about for a while is how faction's give missions that have materials within them as rewards for completing the contract. Well, Perhaps something to look at is a system like the enginners themselves...having an optional alternate quest reward where your contractor (be it any faction, or they need to operate in a system/economy) provides you other materials that are in a bookmarked blueprint, but at a cost of reputation for that faction. not sure if this has come up before but hey, throwing my two cents out there I guess
