Please no. Crafted items are already massively time-gated, adding even more stat RNG to them would just be cruel. I agree there should be more synergy, though. I'm currently considering replacing my Engineering hut, because that's the one of my profession buildings that benefits the least from extra mats, because the crafted gear it makes is either super niche or utterly useless until upgraded, and I can craft toys/pets at a decent speed even without the work orders.
