If it does, I reckon they'd want to keep it simple and keep the Aliens recogniseable to the public at large. Maybe the feeling will be that the proportion of people who know that the Alien takes on the characteristics of the host isn't that large, but "everyone" knows what the xeno is supposed to look like, AL III EN withstanding. (I wonder if more people have seen that or AvP. Interesting and probably unknowable *lol*)
