The Kirin-Rasenshuriken combo would be unlikely to work on Kaguya, since she herself has complete control over nature (as the incomplete Ten-Tails she could even cast this which definitely surpasses the Kirin-Rasenshuriken combo).

the thing about that is that it only works that way in Naruto logic dictates that if you can spiral your own normal chakra you could do the same with any elemental affinity like how kakashi created Chidori by focusing his lightning affinity until it becomes visible. if he did the same thing but at the same time began spiraling it every direction it would create the form of a rasengan eventually he would have a Raiton rasengan
