To be honest, I think there's very, very few teams in the history of test cricket that could have beaten Australia at home the way they've played over four tests so far. There's not a single player that hasn't had a significant impact on the series, excluding perhaps Damien Martyn, who Symonds replaced with success. So no, I don't think England had a realistic chance with Australia playing at their best, especially without Simon Jones.
They certainly had the chance to go a lot closer than they have though.
