I was thinking that the Uchiha KG is interesting that it gives you auto Fire Ninjutsu. I Believe it was Mihamaru i saw suggesting Haku's Ice Jutsu, so If that gets put in it could have Auto Ice Jutsus also, with the Secret Techniques added on. Couldnt we also do something similar for, if not all, at least most of the Normal Jutsus? There is already:
You are born as Lee/Guy of the Lotus and Specialize in Taijutsu
So maybe...You are born as Shizune/Tsunade the Medical Ninja. Skills might include Poison weapons and 5 Auto Medical Points, while the second Stacking would have Massive Strength, Souzou Saisei, a Paralysis Jutsu and a more convenient Shosen Jutsu
There could be a reworking of Suna to do a KG for Gaara ( who i believe has a KG for suna without the shukaku) ect for the rest... or just a few maybe... Comments?
