That was too snarky. But seriously, they are supposed to be in the same universe and time period. What I would do to drive the story is [Cut to Earth / post Aliens action]: Show the BR Los Angeles with the familiar themes, including "Offworld, Find your Paradise" blimps. Have a low-mid class bar (indoor/outdoor) with a sexy/tough couple barely fitting in. They are pretending to drink and cuddle, but are watching a newsfeed of the ALIENS story, but the facts are wrong, total propaganda, then the news moves on. INTRO: A woman meets them, this was planned thru backchanels, she is mid-management for a Wayland competitor. They want to scoop the bio-weapon but dont know what it is, or what exactly went wrong with the Weyland attempts. Our super solid couple are replicants, and the entire story is a crew of replicants with one human embedded, from the competition company. Maybe this is the replicant Mfg, explaning how this crew is self-determined. The entire story presents the future of humanity/humane growth as a set of conflicts between 'natural' humans vs Mfg humans vs. Xenos with a late mixing of Engineers and maybe even a Pred ship.
