Alien Engineers (script wise) was designed to be a shlocky tribute to Alien and Aliens, and the aesthetics and expectations. It was a bit more post-modern, I could imagine some of the scenes being pulled off with absolute sarcasm. Like, for example, Watts getting her leg impaled by the Ultramorphs tail, so she jabs an electric saw through it and manages to go away limping. It's hardly serious, it turned absolutely everything to 11.
The route they decided to go with, was a bit more somber and serious while putting the PoMo conceptual aspects in the background, as was always the case with Alien films. It decided to be Post Modern in its adaptation of old Modernist science fiction, like Forbidden Planet and It! Terror from Beyond Space, and of course Dan's original drafts of Alien. It decided to become more commentary of what it was, than tribute to all it was.
So based on the totality of how different the concept and execution of both are, despite sharing an overall story, I can't see how they could go in that direction. The two writers were going for two completely different ideas. One bathed in its own ridiculousness, the other didn't. I'd imagine, at most they can borrow some scenes, and perhaps tone them down, at most.
