failover between two different firewall brands

in Off-Topic
Greetings all
I want to know if any of you have ever done a wan failover configuration between two different firewall vendor. Specifically between a Sonicwall NSA 240 and a Pix 515. We are migrating off of the Pix as our primary firewall solution but I would still like to keep the pix for fail over. Has anyone done this? Is this even possible?

If it is possible, it's probably not going to be easy to get working right. I used to work on SonicWall stuff. I'm definitely not a huge fan of theirs.
