The possibility is high.  :-)

Here - try something like this:

route {

    ...

    if(is_method("INVITE"))
       route(1);

    ...
}


# -- Relay INVITE -- #

route[1] {
    t_on_failure("1");

    if(!t_relay("udp:proxy1:5060")) {
       xlog("L_INFO", "Final relay failure!\n");
       t_reply("503", "Service Unavailable");
       exit;
    }
}

# -- Backup INVITE route on failure of route(1) -- #

failure_route[1] {
    if(t_was_cancelled()) {
       xlog("L_INFO", "Transaction cancelled.\n");
       exit;
    }

    append_branch();

    if(!t_relay("udp:proxy2:5060")) {
       xlog("L_INFO", "Relay to proxy2 failed - not so good!\n");
       t_reply("503", "Service Unavailable");
       exit;
    }
}
