@Necromunda that theory has a lot of flaws in it Isshin got his power back before ichigo could use hollow powers and the only thing that's canon in this story are the Zanpaktou sprites and finally Muramasa said he killed his owner
tite kubo said he wanted to do a arch for his and Ryūken Ishida past so you will get morw info on him soon
