All of Whitebeards crew members were crew members of his 22 years back when they faced off against gold roger. The admirals were vice-admirals already too. (see ohara incident) The shichibukai would still have been rookies(hancock would have been 9)...

Overall the mass strength of the people who fought in the war would have been less, but the strength of the really important people, whitebeard, garp, sengoku etc. would have been higher...Would be interesting to see how it would have gone.
