One weakness with this idea is it depends upon WIMP theory. This is where the DM particles are weak interacting and Majorana. They are their own anti-particle as a result annihilate themselves. The problem is that detectors means to find WIMPS have come up with nothing. DM appears to exist, but it may not be a weakly interacting particle or WIMP.
