It would be cool if they did something like a banquet but incorporated crafting into it for the FC house, maybe like Once-a-day instances where you could use people of all different aspects of DoH to create a feast that gave you some kind of temporary boost along the lines of FC boosts for credits. Because let's face it, we can't spend our credits fast enough the way they are.

Incorporate the use of Credits to make small, medium or large size banquets (depending on FC size) as a one-off instance that everyone can participate in.

Example: Medium-size feast 11-30 FC members. Make a large roast that will give the FC increased food length for up to 2 hours. How well your FC performs it's various tasks determines whether or not you get the full bonus.

Alchemist: synthesizes the wine
Weaver: Origami napkins
Culinarist: obvious
Carpenter: Carve wooden plates and bowls
Goldsmith: create utensils, option to upgrade carpenter's plates to China
Blacksmith: stokes the oven to keep the temperature right for the Culinarist
Armorer: meh...think of something
Leatherworker: tan hides to make placesettings

Just thinking off the top of my head while trying to leave work, but you get the idea. Something like this would be awesome, I think. It would take us away from the constant grind for a few minutes and give us the opportunity to converse with each other outside the setting of the game. And it could incorporate everything we already do without having to add new features in the forms of our crafters to accompany it.
