Were the engineers headed to Earth to create more cuddles?

Holloway ingested the black liquid from the drink served to him. Went on to have sex with Shaw and voila - Cuddles was born, the engineer was "facehugged" and the proto xeno/deacon was born
Now maybe the plan with the liquid was to taint the water supplies with it to create this on a much larger scale - which is the only other logical way that proto xeno/deacon could be conceived surely? They would then harvest their creations and try to create the proto/deacon from therein?
Was it just history repeating itself from the sacrifice scene at the top of the film?
