This can be done now actually by running multiple Samba instances.
I'm guessing your already knew this, but just in case....

Sounds interesting, but this is only for name registration right?
Effectively you could just run one smbd using netbios aliases
and then run a separate nmbd instance per name (bound to a specific NIC)
and get the exact behavior you are asking for.
