Surely in that situation you'd run batman-advanced in a topology where
you only sent batman-encapsulated packets over your unreliable
ethernet (which is unreliable in a similar way to adhoc wifi), and
then either configure up your bat0 interfaces locally on every host or
bridge the bat0 interfaces to nice reliable local ethernet networks.
Then batman would automatically choose the best path over the
available networks to connect your islands of reliability :-)
