That's my biggest fear, that once we start treading on territory this complex (solution wise), it may be difficult for anyone to actually grasp. I think the simpler we can do it, the better. Still something that is worth to consider, should we find an elegantly simple solution for it.
What if, as I suggested earlier, two snaps are merged when they link directly to each other, the younger snap becoming a related link to the older? It could provoke a button to confirm the merge. It could be broken if one or both remove the link. Both keep their rep with the older snap joining the tribes from the younger snap. That has the benefit of not requiring moderator intervention.
