I'm glad I found this topic as I was about to post the exact same request! I can't believe this hasn't already been created. I've been searching for a mod like this for days. It doesn't have to be functional at all, just purely for looks. Just imagine how cool it would look to have a big rifle on your back, a big pistol on your right hip and maybe a knife or a frag grenade on your left hip! Only one weapon would be equipped at a time, the others would just be there for show. There would have to be some kind of menu integrated into the pipboy menu system to choose which weapon is equipped and which weapons are there just for show. Assign each area of the body it's own slot to determine which weapons are placed there. This could be done with FOSE. The weapon on the left hip could never be equipped and would only ever be there for show as an animation for equipping a weapon from the left hip doesn't exist yet. Just my ideas. I want this mod so badly, if I had the skill I would certainly make it myself!
