I don't think I would bother with a new shotgun at all. Waterfowl are a lot less sensative to trends in fashion than hunters are, I would get a 26" or 28" barrel for your Browning Gold and have at it. The difference in camo will make no difference in the world. Heck, many, many guys still hunt with a camo pattern of bare metal, worn bluing and rust and it works well enough as long as you keep the motion to a minimum.
