I don't think the cons would last very long against the nids mainly because the nids don't have to worry about destroying them to the point where they can't be turned into bio mass but still the Cons would fall to a ripper swarm because they like to take apart metal.

But remember, Energon is toxic to organic life. So they would be poisoned as the Energon from the Cybertronians spilled on them.
