How to sync config to a different data center with a different network topology

Seems like every couple years I ask this question. One day I hope to get an answer :)

 

We have a data center available for the rare times that we have an emergency (usually hurricane) It has a completely different network topology. Is there any way to sync the config of everything from our production HA pair to the LTM at this failover site but exclude the routes/ips and without bridging the network?

 

Thanks,
