I fully endorse this! It would be awesome if you could have a clan color scheme for your ship, so in the load screen, you all fly up into your big clan ship like a squadron, and then as you head off to a mission, it shows you all launching together toward the planet. Maybe you could deconstruct things in your clan ship for glimmer, and the weapons parts/etc would add up. You could also collect other random stuff like that steel plant stuff and parts from armor... after the clan has collectively added enough to the pot, your clan vendor could have a purchasable engram which would decode to a special clan item :)
