Just because the Amalgums were given alien DNA with Kevin's power's doesn't mean Ester went through the same thing. In fiction, aliens that look similar to human, like the Kraaho, have often been able to reproduce naturally with humans. Though there likely is an artificial methods to create a hybrid baby if the parents are not naturally compatible.

As for your theory about Ester trying to get close to Ben for the Rooters, I doubt it. They already had Kevin there. I think the Rooter conspiracy has made you slightly paranoid and you're seeing connections where none exist. And even if Ester was some sort of sleeper agent, the Rooters no longer have the means to activate her. Everything concerning the Rooters was wrapped up in in the Weapon XI episodes, though Derrick J Wyatt did confirm Aggregor and Ragnarok likely had some sort of part in it as well.
