I doubt they would bring back Jiraiya. They didn’t bring back for the war, so I doubt they’d have him turn out to be another character. Kashin could indeed have some connection to Jiraiya, but I doubt he is Jiraiya himself.

I’m pretty sure Kishi wanted Jiraiya’s battle with Pain to be his last time to shine.
