Lightning casual meshmod project WIP

Well, this is one of my most dificult meshmod...variation....!
First, )the model on the left side with an umbrella)head is supposed to be an upgraded version... I doubled the hair, so it's look better, the idea coming from a felow deviant ), but it simply not appearing after I combine the mods together....I don't know what to do...

I mean, adding head is not that hard, but adding the jacket with arms is a second level.
My most serious problem with this: I hided the boots (I know, stupidme, it's belong to the jacket, and I can't separate the meshes in xps...) inside the torso, what most of the time not visible... most of the time...
If somebody can help me to remove those unwanted parts from the inside, I can release this meshmod too...
If not, remains my private model.
