So, you are beginning to yearn for the "good old days" heh ?
Why don't you petition Abbott asking him to bring back Howard and Costello if he wins the 2013 election ?
or, if Abbott wins government, get a NSW Liberal senator and a Victorian Liberal Senator to resign from their Senate seats so that Howard and Costello can be appointed to fill their seats and Costello be appointed as Abbott's treasurer (you think Hockey will give up that job without a fight). the hard question is going to be, what to do with Senator Howard ?
But of course, none of the above will happen. The Australian public gave their verdict in November 2007, "bye bye".
