That is just about the worst case scenario!
Hopefully you were shooting in raw? If so, you might be able to adjust the white balance to make the skin tones right on the closest subjects. Have you tried that?
If you find yourself in the same position again, try a Gary Fong Light Sphere. That will soften the light a little, which should help reduce skin shine, and try it pointed up as well as directly at the subject. Use a high shutter speed (160th or higher) to completely eliminate any ambient. Set the WB at flash. At least that will get the skin color right. It won't be perfect, but it should be useable.
