Sounds like you want to do actual industry, with the development stage and all. As in, an armorsmith does not make weapons. Instead, they sit in a library and draw pieces of armor, which becomes a Blueprint item. That blueprint is then used at an actual forge to produce the needed equipment. Interesting idea, to be sure, especially if the blueprint had a chance of being consumed during use (can't just make a stock and then store them away!) This would essentially take crafting out of the apprentice/trade era and into the industrial era. Of course, some things are simple, after all a helmet is just an upside down bowl, but a padded, ventilated helmet with maximum coverage and lightweight frame. That would be a bit more complex. As an added bonus, some specialized factories could come about, like the Armor Forge, which requires something fire-safe, maybe a few pipes, an anvil, and a metal box for good measure, and also requires the blueprints for each piece of armor to be included in the actual construction, effectively turning these loose pieces of paper into a centralized location to streamline productivity.
The only issue I can see, is the product's end value. A masterwork helmet blueprint may produce a no-quality helmet, because the factory worker has no significant skill. This may be mod-able within the regent area though. I feel though, that the literature side of things could use work. If there were reactions to change mood, that would be wonderful.
