From an evolutionary standpoint, while your theory might work in the long run, it is still impractical.

When talking about altering the hormone cocktail, it is way more easy/practical to influence the nest keepers ro have the required agression potential to defend  the nests as well as to attack people to supply their hive with new nesting supplies. Plus, they can simply swarm out and infect more people.

Altering the fertility processes of human beings to a degree that they can produce enough viable offspring to form a population of bred nest keepers would be an ass-long evolutionary process compared to that, and thus impractical.

Also, empathy does not automatically mean capability of taking care of an otherwise helpless being, because the latter also requires some degree of awareness and responsibility.Little children, for example, will happily tend to a beloved pet and feed it with treats all day, but are still incapable of keeping it  alive and well over a longer period of time on their own.
