I've come up with a new idea for the "Second War of the Worlds" universe. In this iteration, the Martians have sent their team back in time to a point a few years earlier than the initial invasion. Actually, many years earlier - about twenty years early. And they send children in the insertion team - their mission is to completely blend in with the Americans as sleeper agents. Except, of course, children tend to develop their own loyalties over time.
