We don't currently allow TCL expressions in the fallback profile attribute. I think this would be a good feature to have so we will see if we can have this added to a future release.

In the mean time, you can set the fallback host using the rule HTTP::fallback Here is an example... 

when LB_FAILED {   
         HTTP::fallback "http://siteunavailable.mysite.com/index.pl?SiteName=[HTTP::host]"   
 }
