Blender: How to make shoulder pads go along arm skeleton?

[deblueseven]

Rather than torso? I freaking hate a lot of armors that has shouldpads because of how huge and how far the stick out. Would be better if the just laid along the shoulder instead of like some bridge, especially with Power Armors. I'm trying to make them follow along the arm skeleton. For exapmle the Centurion armor, the legion has what seems like T45 arms, a shoulder pad that is along the shoulder, I'd like that for every shoulder pad in the game but I don't know how to blend those kind of things, what to do

 

Edit: Actually I managed to make it but now I get serious clipping, if I try to make the entire shoulderpad switch to upperarm skeleton, there is a severe seam at the torso to shoulderpad. Any ideas?
