One trick that I've used in the past is to raise the common pin of the regulator using a zener diode. But this seems wasteful if the goal is battery charging. I wouldn't expect the need for a terribly well regulated supply and would think that you might be able to find one of the newer charge control ICs which could be a better starting point.
