virtual I.P on PiX DMZ interface

I have 2 PIX firewalls ...
I want to know that just like we have virtual I.P's in HSRP and clients point to that virtual I.P, can we have something similar or like that in PIX firewall as well ? Reason am asking is because the scenario is where ive two PIX firewalls and behind each fix pirewalls is a router (smthg like this given below)
Router 1--> Pix 1--> Internet
Router 2--> Pix 2--> Internet

I want to run HSRP on both routers and only issue I see is that in case of an hsrp failover (i.e. router 1 fails and router 2 becomes the active one), servers in dmz will keep forwarding traffic to Pix 1 DMZ Interface I.P (coz its not gonna know when the HSRP has failed over) whereas it should be sending traffic to Pix 2 DMZ I.P since thats the active one now !

Was i able to explain the issue ?

PIX has HSRP as well, it is a licensed addition however, and only available on the larger PIX's..

I hope you're not referring to HSRP as Pix Active/Active failover configuration ? because that's what I already have ... I am talking about the HSRP with conventional standby commands, etc

wouldn't a least cost route give you the flexibility you need there?
PIX to use router 1 as least cost (10) and router 2 for the next highest (20)..

or if i were to rephrase my question, it would be "does pix have any other way of redundancy except for active/active or active/standby" ?
