So these are the changes I made:
-Naoki is around 5.5 years older than Naruto.
-Itachi is 7 years older than Sasuke and 2 years older than Naoki.
-Shisui is 5 years older than Itachi and 7 years older than Naoki.
-Kakashi is is 5 years older than Shisui, 10 years older than Itachi, and 12 years older than Naoki.
-Hinata Hyuga is 1 year younger than Naruto, and 6 years younger than Naoki. There's a reason for this which you will find out later in the story. She will still graduate at the same time as Naruto albeit being 11 yrs old.
-Temari is 3 years older than Naruto and 2 years younger than MC.
------------------------------------------------------------------
So basically by Shippuden they should be:
-Naoki is 21 years old
-Itachi is 23 years old
-Shisui is 28 years old
-Kakashi is 33 years old
-Naruto is 16 years old
-Sasuke is 16 years old
-Hinata is 15 years old
-Temari is 19 years old
-Karin is 16 years old
-Garaa is 16 years old
-Kankuro is 17 yrs old
----------------------------------------------------------
Although same character are like 2 years older than Cannon, it really won't change anything. It's just so it fits my timeline better.
Expect Senju/Uzumaki clan building and also Uchiha.
This means that Senju and Uzumaki will rebuild itself.
And the shinobi world will remember and fear the power of Senju/Uzumaki and Uchiha clan like they did during warring states.
Also, I won't reveal who romantic interest is, as that will happen later in the story, more towards Shippuden time.
