Roxul (rock wool) Drainboard can be used in what is typically the one inch  
air space behind brick veneers.

Oftentimes mortar droppings clog the air space rendering it ineffective at  
its intended task so the installation of Roxul in that space eliminates  
that possibility while still allowing drainage to take place. (WatJohn did  
a paper on the topic when he was still a student IIRC).

If removing the wood lath and plank sheathing is an option, then  
installing Roxul batts would be a very good option, I think ... especially  
if the planks can be salvaged.
