Yeah, I don't think it would really "screw things up" if it were used properly. If they showed a whole horde of Aliens running around egg-morphing people, with no Queen in sight, it'd probably be a little jarring for audiences who are used to seeing a Queen laying eggs. You have to remember, your basic member of the public hasn't seen the egg-morphing scene unless they caught it in theatres for the 'Alien' director's cut theatrical release. Even people with only passing knowledge of the Alien films, even if they haven't seen them, know about Alien Queens though. My mother has never seen an Alien movie and she knows Alien eggs come from Queen Aliens.
