I am thinking of upgrading to 12c clusterware if it is not too painful and reasonably stable.. Certainly this will be the option I would consider if I decide not to upgrade the clusterware.

They both are independent networks (its a requirement based on the legacy networks we have). I need the listener for the second database to be listening on Network_B. I've done something quite similar to this in 11.2.0.x RAC. The same databases were involved, but two different networks, internal and external. That was a couple years ago, just looked up my notes and found the Oracle Support document: How to Configure A Second Listener on a Separate Network in 11.2 Grid Infrastructure [ID 1063571.1] As I recall the note was a little unclear is spots, but we did get it to work.The method is not entirely straight forward, but is supported, and once setup works as expected. I would point you to a blog if I had written one ( shame on me ), but I did write an internal document that I think could be easily converted to a blog. If this note seems to cover it , feel free to ask any questions you may have about it.
