I think the most long term entertainment would be"Hazou, Noburi, Keiko, and Kagome peggy sue back to the start."
Yoinking Mati outta there immediately with a hasty WE KNOW would be pretty humorous, though I think its a coinflip whether Kagome would come sprinting through the camp on Skywalkers to kidnap us and blow up anyone standing in the way, or if he would just stake it out and wait for Hazou to start shit with the Liberator mess since for all he knows, he's the only one who remembers.
Noburi would be extremely freaked out. Hazou would likely be pretty resolved to not fuck everything up this time, and Keiko would have an existential crisis the likes of which we literally could not fathom.
Operation Lets Do the Time Warp Again would not go off without a hitch.Neo Mari would be beyond suspicious, Saving Akane 2.0 might end up with all of us dead and Iron on fire again, and it would ironically enough probably be quite difficult to gain Jiraiya's trust since we're no longer the lovable goofball sealmaster prodigy who also slam dunks the ball through the floor with a 1:20 frequency, especially if we just shovel superweapons at him.
Also, failing literally improbable events occuring, Akatsuki is still 2-3 years of work away from completing their masterplan, more or less. Once they get fed up with waiting for Yagura to stop turtling up (lol, isn't that funny?) in Mist and start a war to get at him, well, stopping them becomes more of a pipe dream.
