It should be possible.  You can have the routers ping the interface
address of the remote for both links and you can tie static route
to the result of the ping...

I haven't tested how to setup a track object for two remote IP addresses,
so that might pose a problem.

This should give you an idea what can be done:

(even if the URL says 12_3, it applies to SXH and SR* as well)
