I did up 6 examples, all calling on the first. These are fairly disgusting, but I prefer the 5th one over all the rest. The 6th uses the texture I had originally sent, while the others use the second set of textures. All are quite nasty, but one or two are not good quality for animating.
These make my wife cringe and make that noise people make when they are disgusted.

So disgusting
Note:
I did not remove the bloody spurt emitters, but it did ask me on export if I wanted to delete some zero-face objects. You may need to put them back since I have no idea what they were for. Sorry if that caused any trouble.
Also, you can see where the arm nodes meet the body, the texture is stretched. This is because the base pose is not that of the idle pose. I'd personally use it as is, but if need be, somebody better at that kind of stuff could modify the texture at those locations.
