I agree with the last statement you made Sal Shunsui's bankai is most likely far to dangerous to be exposed look at Soifon's it cause an explosion that wiped out like half of the city and she is one of the younger captains compared to shunsui and ukitake also Urahara made the comment when he was training chad that his Bankai was not fit for helping or training which could lead you to believe that fully realized bankai's are used for one on one situations. And who are you to say that my theory is cracked, NO ONE made any indication of being alarmed at Isshin's presence if he was an unknown factor as you are hinting at when he first showed up to defend Ichigo everyone would have been completely confused as to who the hell this person was and why he was here seeing as how the FKT was planned by yama-jii he had to have known about Isshin prior to making the plan.
