I liked the second and third idea, the first idea makes me think that it will be a "slice of life" but I find it strange that it is a "slice of life" of ninja characters, a work full of action, adrenaline and risk of death, in addition Furthermore, with Tsunade, this would be very difficult since she is an important figure in the village. As for your third idea, I would find it interesting but only if she had some kind of ability like Tang Lian's to grow an artificial *****.
