I've read your post but I'm sorry to say that I'm still not sure what it is that you want - you're throwing so many things together there that I'm at a bit of a loss.
You seem to want something that makes you stand out - "bragging rights", so to speak. Something that "marks" you as a mastercrafter, similar to how Ultimate-weapons might be used to show off success in battle.
At the same time you want something that benefits you when it comes to the actual gameplay, aka crafting. This is were I wonder most: Do you want something that makes current crafting easier (aka: current gear can be crafted using gear that anyone can obtain, but its made easier if you get this "special gear") OR do you want recipes that you outright cant craft without the special gear? Or in other words: What would be the motivation to obtain this "better gear", this reward? Why should I want a better frying pan? What would you lock behind this?
Maybe our missunderstanding here stems from the point that I dont consider gear in itself a reward, its always something to achieve something - may that be looks (glamour), content made available in the first place (ilvl-locks for battle classes; crfatmanship/control requirements for crafters), content made easier (reaching sweetspots to use certain rotations etc.) or really just to show off.
I'm really confused by your claim that you want things to show off - but at the same time you dismiss stuff thats made for that purpose as not worthy rewards. You talk about difficulty, but want luck-based content back.
At the end of the day I would like to see more challenging crafting content aswell - it took me maybe 30 minutes to figure out a new macro for the new crafts this patch and 10 of those were spend on hunting down typos. I can see where our missunderstanding comes from, though: I enjoy a challenge for the challenges sake, I dont need a trophy at the end. Which ultimately seems to be what you're after...?
