I think that using the lowest MAC address on the node is a pretty good
solution.  This is similar to what layer-2 bridges do
when they implement spanning-tree.  In practice, this works well.

Yes, there are certain MAC address ranges that can be "reprogrammed".
You'll have to decide if this is a show-stopping issue for you.
