I think there are some implications with the ISDN interface being in backup mode - like IOS idling the interface. You could just use a floating static route to dodge that issue - works as long as you don't mind the ISDN not being tied to the serial interface and the effect should be the same - works whether you're looking for dial backup or you can leave ISDN up all the time.
