I see from the animation (thanks for the format change) that your using a normal texture, so the modifying the OBJ file thing wouldn't apply.

If you have P6, it should be possible to write a Wacro script to do the changes, though whether doing so would be quicker than doing them all by hand depends on the nodes that need changing being named the same.

If you want to do this kind of thing more than a few times, you should look at getting ShaderSpider from DAZ (P6 only).
