You are going to have problems with this running HSRP I think. Even if you track the state of the Ethernet interface from which you receive your primary default route, if there is a soft failure on their side you will still not be able to get out because the active router will have no reason to go into standby because the interface is still up, and I don't believe there is any function in HSRP to track a route. Now, if you have one router with 3 ethernet, you could run bgp and it would dynamically change over if you lost bgp with the primary router, but that brings you a single point of failure. In this situation, there are some games you could play with OSPF on the inside of your network with 2 routers. You would have your machines point to the primary, and if it loses its default route you could configure it so that the default route from the backup gets installed in its table and it will send all traffic to the backup, and then revert to the old condition when everything goes back to normal. You could also do this with other protocols.
