Honest to god, I don't know where this focus on Isshin's blood is coming from. He used it for ONE ATTACK. Grimmjow used his own blood for a Gran Rey Cero, does that mean Pantera was actually blood-themed and we just never saw it? Yamamoto sacrificed his arm to Ittō Kasō, is his powerset actually sacrifice-themed and not fire-themed?

Like I said, the most likely scenario is that Isshin's Bankai would look/perform something like Tensa Zangetsu - pre-timeskip, post-timeskip, take your pick. It's energy-based, he can use Getsuga Tenshō, all the signs are there - this blood tripe is irrelevant.
