It's a nice idea, but due to the nature of the Nomads, I just don't think it's possible. Although I do think that the Wild should include people and ships from other houses. We never know what happened to the Libertonian, Bretonian, or Kusarian Wild Fleets after the war. Maybe they met up with the Rheinlander Wild group and joined up. If this is the case, there should be more ships available to the Wild, since people from all the Houses are part of it.
