Okay, I've found out a couple of important things:

1)   All "Map" strings are followed by "NO_MAP", and searching for "jpg" and "Textures" both returned nothing. 

2)   The slave morphs are keyed to the internal names of their masters rather than the dial names.

Also, I'm not sure why you're talking about PZ2s, because the only PZ2s are the INJ/REM poses for the third-party slave morphs.  The figure itself is in the form of a CR2 and PMD sharing the same directory.
