Those look pretty cool if you ask me, though one could argue that creating surfaces that have very clear marks (like the last one) is going to make it easy to recognize them as a tile when repeated - very complex textures (with top and botton, or a certain mark in the middle like a patch of missing mortar (with exposed bricks)) are welcomed (by me anyway) when they are vey big and can be used to cover an entire wall - but they do need to be made based off an existing "bland" texture, so you can tile the specific one inside a composition of others.
As far as the team, I'll leave it to them, but if you take me, I've come up with a couple of simple models (a bench and a window grate), untextured, and I intend on simply releasing/contributing them to the general forum as is, so anyone can pick them up, and either finish it off and release it again to the community, or use in his own mission - this would share the work load, you get something that already has a base for you to complete, and I dont see why you couldnt do the same (just keep releasing them and someone will surely pick it up and use it on a map, or maybe give it the bumpmaps and whatnot, etc).
