bBUt would Kori still be the same thing as hoyton. Hoyoton allows a person to makes ic by using water and wind chakra )i.e. Haku). SO wouldn't it be more probable for her to have Hoyotn instead of a bloodline of Shadow and MIst. Also if she had a Hoyoton bloodtrait she could technically learn rasengan easier because she has an affinity to wind chakra. Also along those lines if she had the affinity to wind and water chakra she culuse water prison jutsu with one hand and hit the person with the other hand using rasengan. even though that also would drain a good deal of chakra.
