Maybe, but to me that seems like a explanation of Gamma Bay Bursts, FRB's
are something different, a single immensely powerful millisecond radio
pulse with no accompanying gamma, X-ray or optical emissions. Of the 60
known FRB's most never repeat but 2 of them have which would rule out any
sort of catastrophic collision, at lest for those two, but we may be
dealing with two different phenomenon with two different underlying
mechanisms.
One idea involves a very rapidly rotating neutron star of more than 2.2
solar mass but less than 2.7, normally such a thing would collapse into a
Black Hole but not if its spinning fast enough; however its its powerful
magnetic field would gradually slow it down and when it reached a critical
point it would collapse and form a Black Hole and maybe produce a radio
pulse. But of course something like that couldn't repeat and at least 2
FRB's do.
Another idea for the cause involved the decay of Axion Miniclusters, but
of course they couldn't repeat either:
Fast Radio Bursts and Axion Miniclusters <https://arxiv.org/abs/1411.3900>
Yet another weird idea involve superconducting cosmic strings, maybe that
could repeat.
