Given how much rotating black hole differs from non-rotating one I believe a black hole consisting exclusively of swirling photons could have some very unique properties that out best models don't necessarily capture. For example some resonances that could expell enough energy through gravitational waves to make it unstable and explode into a version of a big bang.
