Ok. Do these routers have SNMP support ? e.g. could you query the interface port status of these routers through an snmp-get call ? If yes - it would be easy to set something up. Check the interface status (routine to cycle through the results). If one interface is down - issue a command to reroute the traffic through another gateway ...
That's what I did when I was still working at an ISP... Don't have the code anymore - but it really was a 50liners written in perl with netsnmp support. Fairly easy.
