We needed the exact same functionality and we ended up writing our  
own internal patch for this purpose.

Instead of entering only one host for the domain controller you can  
enter a comma separated list of hosts. The filter will try to connect  
to them one by one and use the first that is accessible. You can also  
set a timeout and a port, both used for probing.

We would be more than happy to contribute this small patch, is there  
a formal way to do it?

You could subclass the filter and have it read its configuration from  
a properties file or similar.
