I recall J'onn managing to make a bunch of white Martians kick the crap out if a bunch of other White Martian, thinking they were actually beating up the JLA. So he definitely could use a similar tactic here. It wouldn't even take very long to implant. But Surfer still probably won't give him that shot, especially if he opens a singularity.
