Well, Sideshow finally posted a pic of their exclusive AVP warrir alien by Hot Toys. The link is below. I'm not pointing fingers, but this is not the AVP warrior, which was predominately black and sepia tones. This really looks more like the Amalgamated Dynamics Alien: Ressurection warrior based on the paint scheme. There are no pics of the legs, but if memory serves, this particular beastie had legs similar to a dogs. Maybe that will be the substantiev modification. Anyhow- for what it's worth...
