Would never have thought they'd actually dig up/strung up the Alien's corpse beating a dead horse or in this case xenomorph to harvest more material to milk that cash cow, it may work in context, it sounds absurd but it's a poetic analogy. It could come across as ridiculous or an intriguing callback. Can't think of the last time a character seen floating through the vacuum of space and picked up by a ship to safety wasn't ridiculed by a fanbase.
I'm unsure how the Ian Holm Ash inclusion will be pulled off, I kinda give it an odd because the character was an artificial intelligence, hope Ian's relative provided permission to his likeness and were compensated nicely.
