I would sort the best of the matching numbers frame and lower end, then the absolute best original parts for everything else from the entire stash, and focus on restoring that bike.
All that remains could be built into a cafe racer, street tracker, off-roadrer, race bike, or whatever custom you desire.
Personally I would have one with downswept pipes, the other with upswept - best of both worlds.
