I have to agree with some of the sentiment here that if it is going to take 30-40 or more green items re'd to get a blue schematic, then this type of crafting really is useless, at least from my perspective as an artificer. While I burn through resources, credits, and time to struggle to get the blue schematic for a level 49 bastion enhancement, or a level 49 guardian hilt, I can instead go and earn credits, legacy xp, and get loot drops doing daily Ilum and Belsavis quests to get daily comms, and buy the purple level 50 bastion enhancements and guardian hilts.
I guess I'll leave the RE'ing to those that enjoy the frustration.
