Wouldn't look good, trust me on that, I've tried. The weighing process isn't the issue it's the fact that a single part of a model can only have 999 verts. These models are way too detailed to use anything other than a head, backpack, etc. The torso alone probably contains 10,000 verts by the time you reduce it down to under 1000 it gets deformed and ugly. Just the head and backpack are from BF the rest is varios JA assets. That's not the issue see top of this post.
