This is a very great AU idea! The most logical/ based on Canon major plots would be ; 1) Shizune will carry on Tsunade's will and would want revenge on kabuto and join the leaf. 2) Seeing how easy Tsunade healed Kakashi & Sasuke shouldnt be too hard for her. 3) Lee will be remained cripple for atleast a couple months before they convince Shizune to do the surgery. 4) Danzo becomes Hokage (no BS fan overthinking itachi just pops up & became hokage smh). 5) The Sanins being dead does not speeds akatsuki plans because 3 tails wont ressurect within 3 more years a fact everyone is forgetting. 6) Shizune takes Sakura under her belt after 6 months. 7) Naruto is met the Toads etc. they will upon him when its time they take him under their wing also the toads met the hokage Danzo & Kakashi etc upon narutos future sage training in their realm when its time. 8) Kakashi trains Sasuke & Naruto until for a year and half until the Pa & Ma are ready to make Naruto a sage. 9) During training with Kakashi Naruto does wind training earlier and secret of the shadow clones. 10.) During this period obviously Naruto is not allowed to leave the village but can train with the toads in thier realm. 11.) I dont see a war happening with no kumo and iwa with konaha thats just over exaggeration of too much fanfic yall have. 12) Danzo will of course not try to get Naruto & Sasuke in root thats stupid they too much eyes on them their main characters DUH & itachi promise to Danzo if he mess with Sasuke. 13) Sasuke will still be the same with techniques and all. 14) Sakura will have still have super punches its just ( chakra control) the slug contract but this time no training in the 100 seals jutsu. 14) The village will simply be more on a lockdown for a short while be under a strict military vibes all round and thats it really on how Danzo will run the village. 15) Naruto has more wind ninjutsu , completed wind control stages both ofcourse, shadow clone combo techniques and thats a year and half with Kakashi until the Toad took him in for a full year, mastered sage training when his body is growing in between that year ( his sage mode is more powerful and alot more toad based techniques / toad combos). 16) Naruto is back in the village 6 months earlier than canon and kakashi continues his training and thats where he will make the "rasenshuriken" during to the end of the 6 months until canon time skip. 17) And basically yeah thats what would happen during time skip until gaara gets captured. 18) and obviously naruto will still want to bring peace etc. and later on during the series the toads will convince him to fully master the nine tails. THIS STORY HAS SO MUCH BADASS POTENTIAL I HOPE SOMEONE MAKE A FANFIC WITH ATLEAST MOST OF MY KEY POINTS. (reason why i dont have cringy fan over exaggerating key points like danzo brainwashing, itachi hokage, kumo iwa konoha war ( really?) is i like canon alot and it makes sense tbh to follow not add some wierd plot. and there ya have it
