So she would store both chakra and nature energy in the yin seal? it sounds good in theory but i think it has some flaws.

- The Byakugo is activated by utilizing the mass amount of chakra one stores through constant chakra control in ones forehead, which means the amount of chakra could def increase as time goes by, such that it gave sakura the power to contend with tsunade.

- for nature energy to be utilized to its fullest potential, one must Balance the nature energy perfectly or risk Sage mode failing if theres too little nature energy or petrify if theres too much. but that brings me to my third and final point

- Collecting nature energy is only possible when standing completely still, so as long as sakura is moving, her byakugo chakra will increase but the nature energy wouldn't, causing SM to fail.

Sakura would actively need to stop moving and gather nature energy to balance with her byakugo chakra in order to utilize it, therefore the only way to use it is as i stated above, with support in order to gather Nature Energy.
