I Think it would be good, if before the end of the series Sasuke got a chance to talk to Fugaku and mikito, i just think it would be a interesting conversation, sense Fugaku Thought that Sasuke was soft and would just be a average guy and he turned out way differently
So i wonder how they would react to current Sasuke, Plus everyone got closure with Their Parents, Naruto,Kakashi,Ino,Shikamaru,Choji, so it would be cool if Sasuke got to talk to them before the series ends
Sasuke would have to be dying like Kakashi then, instead of his parents he got the Sage. I don't see any other way really, don't know if the Sage even have anymore power really.
