I wouldn't say better than "perhaps physically possible".
You'd need an old neutron star whose void had filled in and we might still detect it from collisions with Oort Cloud objects smaller than planets. These would be far more probable than the very large object collision your scenario needs. They'd still be bright in the more energetic (and conspicuous) parts of the EM spectrum.
