The thing I'm now wondering is if this film could still technically be made? How would it be written to take place after Covenant? Unless Org. 6 turned out to be another engineer world, or David knows of other engineer installations and chose to go there and do this? The colonists on board covenant would allow some humans to still be included in the story. They'd be caught between mutating engineers, military engineers, and an insane David wreaking havoc on an entire city or world.
I see that picture of David staring at the small pods on the table and can't help but be reminded of the seed-pod scene from "the thing from another world". It's so similar it's freaky. Maybe the urns and black goo are an old and outdated weapon. Maybe current engineers would have something far more powerful that David could use to wipe out earth, and he's fighting to get to it. Maybe the derelict from Alien 79 could've been some impregnated engineer escaping as the city falls in this film, only to die and crash on lv-426. Either way, it may take some serious writing-fu, but it would be wonderful if something like this artwork was done for the final film.
