I would say it depends on the Evolutionary Path from Origin ==> Xenomorph
If the Black Goo passes on Acid Blood Traits, then there is a chance the Neomorphs (if they come from the Black Goo) have Acid Blood.
If the Black Goo does not pass on Acid Blood then the Neomorphs may likely not have Acid Blood... but then it would logically mean the Hammerpedes then play the KEY Role into how the Xenomorph came about and not Synthetic Androids..
My Prometheus Re-write was to use a different Fifield, and show he had Acid Blood and so did the Trillobite (which i think has Acid Blood in a cut we have not seen that explains the real reason the Engineer has that Face Burn).
Again my comments i try to analyze logically clues and provide logical responses to every debate... my re-write and my in work Prometheus 2 did the same with the clues.. a little less ambiguous by just adding that slight extra HINT..
