Well, the idea is explored in the West Wing's last season, where Santos decides to appoint his new Vice President once he is elected instead of waiting an automatic confirmation with the vote of the electoral college. I think Bush would've gone by nominating a candidate to carry the VP slot, as Taft did with Nicholas Murray Butler back in 1912 when his running mate died in October.
My favourite to become an alternate running mate for Bush would be Montana Governor Marc Racicot. A popular governor who had finished his two terms by then, he had been considered many times as a contender for VP or Attorney General.
