Honestly, this was before I learned more about hardening. Although, maybe the piercing damage of the kagune can bypass it, because the quinque cuts the metal it is made of very easily.
This Taiyo has LS Class P and Kaneki won't be able to jump a whole LS level, at least he won't be able to do it quickly.
If we use Post-Dragon Kaneki with the initial key of High 7-C and prior knowledge, and also use Taiyo's Low 7-B and give him Momo bullets, then it might be fair.
However, I think it would be better to use the Post-Cochlea version (High 7-C) against Taiyo Blooming (High 7-C). Taiyo still has Class P threads and hardening, which will prevent injury
