Can I use PBR to get traffic to flow from two ISPs to a single host inside a PIX without BGP?

Here is the general scenario. (the IPs have been changed to protect the guilty)
I have two ISPs. In want all outbound traffic going through ISP A. I have a server I want published on ISP A. I also want the server published on ISP B. I have a router in front of the pix with three interfaces to do policy based routing. I have a small block of Ips from each ISP /29. Can I do this without doing double nat (once on the router and once on the PIX)? Is there another way to do this without adding hardware?
