I for one always imagined that if there was going to be another way to get xeno specimens after Resurrection, it would be some spaceship finding a cocoon form of the queen from Aliens drifting in some remote region of space. The cocoon form (protective shell) could be a way for the queen to survive the vacuum of space, while also being in some state of hibernation. They take it aboard without first knowing what it is and bring it to a populated space (science) station.
Then somehow the queen is "unfrozen" and comes back to her original form and starts laying eggs and wreaking havok. Due to Ripley8's proximity and her telepathic abilities, she is dragged closer and closer to the location of the queen. Eventually her mind becomes twisted by the queen's presence and she might or might not turn on the human inhabitants, while also fighting the queen for supremacy.
By the end of it the queen is defeated, but Ripley8 is transformed, both physically and psihically and her former human allies have no choice but to bring her down, in a last ditch effort to rid the galaxy of the xeno presence forever. So you could then say that Ripley lived long enough to become the villain.
