Two-cent plot progression

I think part of the next installment could be about a recovery/recon team that encounters Deacon, while discovering more about the outpost(s)' purpose and the science behind the genetics program. They could also awaken another Engineer(s) in one of the other temple-hangars, resulting in a successful Juggernaut launch (or several), one or more of which could have Deacon/it's offspring (chased away by the recovery team) hiding on board, or some other "accident(s) waiting to happen". The original "Alien" is +/- 30 years later, so one could end up on LV-426 and sew that mystery up nice and neat. The other part could be Shaw reaching another Engineer population center - only an active one this time, infiltrating it and learning about the cultural side. Maybe she could be discovered/captured, or successfully initiate open dialogue, if only for a time. I think there should be at least one more after this one, though. It would consist of Shaw ending up at the Engineer society "core", where she could maybe "self-sacrifice" in an attempt to corrupt the genetics program with her own DNA. Or she might willingly serve as an "Eve" for restoring lost gender-duality to their race, which could work out for everyone, or still accidentally corrupt the system, for a more bleak outcome. There have been questions as to why the Engineers all look male. The Xenos might spring from all that's left of some trace female genetic remains that the Engineers are trying to reconstitute into a procreation-viable gender, through planetary-scale evolutionary crapshoots (e.g., the opening sequence). The Xenos may look similar to the bio-mechanics of the Engineers because they have been able to develop technologically progressive applications for genetic engineering, but only in an increasingly diversive, specific, and mechanical direction, rather than a restorative one. The physiology of the Xeno may simply be the extent of the Engineers' ability to supplement missing information in the genome, and it's all-too-familiar life cycle is the closest thing they can get to actual gestative reproduction without starting from scratch (again, the opening sequence). If they are getting further and further from reaching that goal, the animosity (desperation?) of the LV-223 Engineer would make sense.
