I will do one if no one else has yet. I have a few figures that I have to do this for in the future, so, sure I can do it for you, no problem. There are two or three different ways you can do it, so I'll do them all. Cutting on the seam like Bakit said, hollowing out the waist and connecting the other on the inside or, cutting around a belt that is part of the mold and hollowing out the inside of that.
I usually use these things that look a lot like bone cutters,I just cut along the seems of the figure.It has to be right on the seem or you'll end up messing up the figure.
