You could create a second pool and populate it with the same members however then you can assign your more simplistic monitor. Then you could add an iRule that looks at the availability of the main pool, and if it were to become unavailable then you can send traffic onto your backup pool.

 

You can use active_members to test whether your pool is available or not - either all of the time (so every HTTP_Request for instance) or when load balancing can't take place (LB_FAILED) or a mixture of the two, whatever suits your needs.
