Xenomorphs from series is known for their ability to enhance their host DNA by absorbing/altering DNA to give birth to a new type of creature.
- alien hugs dog so it creates a dog-alien "runner" (alien³) and ripley says
"I haven't seen one exactly like this before, it moves... differently."
- alien facehugs human, drone happens (aliens)
- alien meets predator, predalien is formed (aliens versus predator 2)
Why don't they do it on their own kind? Because they are perfect already?
Maybe they try and they have 10th concentric mouths(mouth opens, another mouth bursts, it opens, another mouth bursts, it opens, until 10th mouth bites meters away from alien)? Even more acidic blood? Then normal aliens fear and attack these so these can't live?
Maybe simply they need more DNA to complete missing parts in their own but can't take their own?
Maybe because their acidic blood stops chest-bursters bursting chests?
Why didn't Weyland Yutani try this? Why own people? They could try with an elephant or some octopus?
Reddit says adult xenomorph simply chews facehugger. What if facehugger is the one seen on the new movie that is a lot bigger? (not covenant2017, the movie before that)
