Let me get this straight: you want...
o - shader that addresses the entire figure at one go
o - shader that preserves the existing colour maps (doesn't EZSkin2 do this?)
o - a mechanism that will manage things like displacement, etc
o - perhaps even a means to automate all this depending on the scene settings

Um, sounds to me like what you want is a PoserPython script to examine a scene, that would then - dunno, possibly invoke a Matmatic script, maybe? Matmatic could generate .mt5s or mc6s, depending on what you want. Just not sure if PoserPython can invoke Matmatic... :blink:

I just think EZSkin2 would be the easiest solution, all around.
