Naruto will not kill Sasuke. He told Itachi that if Sasuke were to attack Konoha he would find a way to stop him without killing him after Itachi told him that sometimes a ninja needs to make hard choices. And that's why Itachi gave him some of his power.
kiba wont be an ambu because he has akamaru. and i haven't seen any ambu with pets. i can see sai, yamato and kakashi as an ambu. neji would make a good ambu because of his sight. ino because of her ability to get information with that mind transfer jutsu. shikamaru and choji can work in the same team because they work very well together. lee wont because he is simlar to naruto as they both dislike going quite.
well his mothers name means whirlpool which would indicate water but i cant see water fitting him. although earth maybe? maybe he could have a jutsu like the guy yamato killed in filler arc (the one that makes his body hard as hell and strong as a mofo) then he could use his rasenshuriken jutsu w/o harm
thats what i mean (in your last sentence) earth would make the most sense to me cuz he could use it to detain foes or for defense and yet it wouldn't over power him. also im thinking that nature maybe considered light element
