Hi, I have HA1 link traversing 2 upstream routers - if one of the routers goes down, both FW lose HA1 and thus; both become Active. Is it possible to configure HA1 backup over an existing LAN side link? i.e. not using a dedicated port for this but using a sub-interface / existing L3 interface etc?
thanks.

There's literally config right next to your HA1 for an HA1 backup. Also, your deployed design of having your primary HA1 interface being over a routed link goes against the stated design of how your primary HA1 interface should be.
"Heartbeat Backup", using your management interface is also a failsafe that you should have configured. Which prevents split-brain.
