if MEGA Construx wasn't fucking around, they should make a tabletop wargame with their micro action figures as the minis and brick build vehicles and scenery. The figures and sets would probably be about half the cost of say warhammer minis. It would probably have to be "baby's first wargame" tier rulewise, probably have only one good guy faction and one bad guy faction, and the sets would still have to be still somewhat playsets so little billy will still have interest in the series.
