SRX320 cluster with LTE mini-PIM failover

Hello guys!

Also posted on r/juniper
I really hope you can help me!

We have an SRX320 cluster with LTE mini-PIM on a remote location.
Node 0 has an EVPN (L2 link) to our hosting in port 3
Node 1 has a LTE mini-PIM with random public ip simcard and ipsec to hosting

What we want:

Cluster running active/active instead of active/passive as it currently is.
When node0 loses link and access to the internet through the EVPN it should failover to the LTE.
It should also failback to node 0 if connectivity is restored.

Currently we have a kind of failover:
set interfaces ge-0/0/3 unit 0 backup-options interface dl0.0

But this only happens if physical link is down, which is not usually the case.
It also takes a while for the LTE mini-pim to turn on and connect - which is why i want it to always be active.

Research says rpm probes and ip monitoring, but i cannot find anyone with this kind of setup.

Hope you can help :)
