Furthermore, having a dedicated interface for ha icl doesn't appear to 
be required to get this working.  I just flipped my config to using the 
untrust interface and its associated ip addresses on both srx nodes

i did "deactivate security zones security-zone halink" and then 
redefined my HA ICL peering to be via ae1.0 (which is my untrust 
interface) and used those ip's.  works.

Just nice to know in case you can't or don't want to setup a separate 
(3rd) interface and zone dedicated for ha icl.
