I belong to a small FC that just got a house and can finally start on an airship. Unfortunately, due to our size, getting materials to build is a massive strain. Why don't FC crafting recipes have a size modifier based on the population of the company?

FCs could come in various set sizes, with different membership caps. Increasing size would be easy, the caps are mostly there to correspond to the various size projects. Projects would be labelled as the size they were built at, so that upgrading your FC for more members would render the previous items too small. A second recipe to upgrade size could be provided using a smaller version as a base material and paying the difference off.

FC crafts should scale the materials based on this size. The current requirements seem fit for maybe 50 people to do comfortably. Adding smaller tiers for 10, 25, and larger tiers for 100, and 200+ would be great. 5 size tiers of FC to make the work a fair split based on the number of contributors you can expect.
