Modding the default Combat Armour

[D0gbert]

As we all know, the shoulder plates of the combat armour are directly attached to the torso of the character, meaning it will not move/rotate with the arm as the character takes aim, making the arm clip thru the plate. That is just an eyesore to look at.

I want to see if I could make the shoulder-pieces into separate entities, anchored to the shoulder, so it will move with the arm.

Is this feat possible?

If so? Could someone give me some guidance? I am a noob at modifying meshes, models etc
