My tip? You have to look into how m2 and .skin files actually work. If you don't know the files you are editing that will do you no good in the end.
Well the only way to do this is DBC Editing for MOP, Unless you want to re-uvmap for MOP. Which seems stupid when MOP Allows WOD UV-Mapping.
I might help you later I'm a little busy at the moment working on a little something for Afterfall.
