Those are some beautiful fabrics....i would say that you could definitely find some different shades of gold and rust/orange that would pull out those colors in the pieces and give it some pop. Not sure i would mix in the one with the graph paper type grid...the others are all "organic" and it seems a little out of place. Not sure either about pattern - but what if you thought of those more as the background fabrics for say the Maple Leaf pattern...or Bear Paw using the colors above.
Good luck.... please post a photo when you finally decide what to make.
