Angstrom Levy sends 18 evil versions of Superman to the DC universe could they destroy the planet or would they all get killed

Like the Invincible War. All versions just fly around destroying major cities like Gotham, Metropolis, Central City ext. The battle is restricted to only heroes on earth. The Superman’s goals are to destroy as much as possible and kill any hero that gets in their way. They have 3 days like in the show and comic. No prep time the Superman’s just get teleported in. How much damage could they do? Would any of the Evil Clark’s live all 3 days before getting stranded in an alternate, dimension?
