Maybe I am just being dense this morning but I am confused why you think
that your nodes are different things depending on how many children they
have (nodes, groups, entities, ahhh!)...
If you have two sets of hierarchies that share the same nodes, you may

Each node will have children etc, and those will have children, etc.
But
