1) The Palm Revolving Heaven needs to be overpowered through raw chakra, or you need to prevent the Hyūga from spinning. Naruto did a combination of both, his clash prevented Neji from spinning any further, and his natural chakra is way beyond Neji's. Naruto had more Natural chakra than Kakashi, to the point where Kakashi says no amount of training could give him Naruto's chakra reserves. Katsuo went the second route and applied counter rotation.
2) Sagisō has no need to match Kiro's speed.
3) He's gonna walk up to her with lightning-fast reflexes and shock her to death, is an asinine argument that you yourselves would Veto later because if even other dojutsu stand no chance at keeping up with him then it becomes unbalanced.
4) Wind is a natural insulator, it trumps lightning within the elements so outright shocking her won't be so simple.
5) Just because I never used it again after battling Kai, you seem to have forgotten Sagisō has her own variant of a chakra mode.
6) You should really do more research on the gentle fist.
