I'll play along.
It'd have a long sloped dome head with the rear quickly forming into a long, slightly armored, tail. The creature's face has no clear focal point as it's ribbed rounded forehead curves underneath it's body. The "face" would be mostly on the bottom of the specimen consisting mostly of just a rounded mouth utilizing a unique second jaw that ejects out towards it's vitcim's face with high velocity whilst it lunges through the air. Meanwhile, the creature sports a set of massive spider-like appendages much like off the original facehugger that it flings outward while attempting to lunge and "catch" prey. It's darker in color, and about twice the size. I would say it's adaptation has made it more difficult to do it's traditional face-hugging and now has become a sneaky, freaky, killing machine, a common characteristic of xenomorphs.
