Conceptually, something like this should work:

vcl_fetch() {
    if (!obj.valid) {
        set obj.status = 304;
        set obj.http.location = "http://error.example.com/php-sucks.html";
        pass;
    }
}

It probably doesn't, though, and there may even be cases where the
backend code issues an error page directly instead of passing control
to vcl_fetch().  This would make a good Junior Varnish Hacker
Project...
