There are two things which come to mind for me.

1. Have you tried the Levels "Auto Colour" setting?  Sometimes that get's rid of white balance problems.

2. No idea why this works (i was playing around one day and stumbled on this) but if you create a new file in photoshop (the bigger the better) and put on the horizontal axis (use the shift key) aspectrum gradient and on the vertical axis a white to black gradient on a different layer set to Luminance... Save as a psd file and keep it open. Then open up the picture you want to change... go to Image>Adjustment>Match Colour - use the colour "map" you have as the "source" and play around with the sliders.

This is what i got with the sliders set to the middle position and "Neutralise" turned on:

This is what i got just using the default "auto colour" setting on the "levels" layer:

But i have to say, nothing beats using a Raw conversion tool with a white balance adjustment

"In every colour, there's the light.
In every stone sleeps a crystal.

Man is the dream of the Dolphin"
