While crafting at Naldiq & Vymelli's in Limsa Lominsa, I watched NPCs Pfynhaemr and M'zimzizi crafting a sword. Unfortunately, I don't think they will ever finish, but watching them gave me an idea.

The ability for DoHs to work together on a single synthesis. There are a lot of Disciples of Hands in Eorzea and I believe a lot of them would love the opportunity to craft in parties.

I'm not sure exactly how it would work but I have a few ideas.

1. Bonuses in yield (perhaps in the expense of xp)
2. Bonuses in xp
3. The ability to synthesize more difficult recipes (perhaps at the expense of yield)

Anyway, DoHs post here if you would be interested in a system like this.
