True, the collapse would have to be very asymmetrical , and I admit that
seems a bit unlikely.

I was thinking maybe 2 sub solar mass Black Holes coalescing. That would be
really cool if true. Black Holes that small would pretty much have to be
primordial, I can't think of anything except the Big Bang itself that would
have conditions extreme enough to produce them.
