Alien Concept Art - Help Required

As some of you may or may not know I am currently penning a screenplay for an AVP Prequel. But I need some assistance... Two pieces of concept art... The first depicting a digitigrade stance Xenomorph from the side with arms, hands and legs slightly longer and thinner than those of human, with a shrunken abdomen. The second showing the exact same pose as above but matching the build of a woman (see below) with condensed/exaggerated versions of the details of the final product on the costume, without a tail and showing the actress wearing power-stilts instead of the Xenomorphs feet. This is because I have envisioned a way in which to realize our beloved Alien creature on screen using the following techniques... - Actresses – Women inside the suits makes more sense than using men. Their bodies, posture, build and movement would compliment that of the Xenomorph. - Power Stilts – The use of Power Stilts would not only give the actresses extra height but also a digitrade stance. - CGI Manipulation – Condensing/stretching the detail on the costumes arms, legs and abdomen, CGI manipulation can be used to stretch and “skinny” the arms and legs and shrink the abdomen, creating alien proportions. - CGI Additions – The feet and tail of the creature can be added with the use of CGI, using reference footage from on-set props. - Animatronics – The workings of the creatures jaw and mouth can be achieved using animatronics, with the head of the creature extending forward and behind the actresses head instead of atop. Although women would ideally be playing the Xenomorphs, their would be no female features. Actresses are only to be used to help accentuate the form of the creature we know and love. To clarify, the finished product would look much like the image below, although less exaggerated, without the "fin tail" and more akin to the design from Alien 1979 and Aliens 1986, with the other piece of concept art showing how that would be achieved "on set" using a woman in the suit wearing power stilts etc. as explained above...
