Well, fine, I'll give you a point for that, I didn't take into account Hiashi's rotation being stronger than Neji's, and while I could argue that the Rasenshuriken's center would work like a Rasengan and struggle before exploding, I will move onto something more beneficial to my side of the argument, and that is that Hiashi's Kaiten could only block so much,FRS would get repeled and explode on impact if slammed into Kaiten by the user , which would likely kill both , if this is Base Naruto when he just learned it.
A larger Rotation like Hiashi's would re-direct and repel the FRS along with its explosion , and would not get consumed by the blast due to its size , leaving Naruto to collect the left-over energy if he slammed into it himself.

I'm doubtful on wether he could take on this Rasengan with a Kaiten, which is far more ideal on breaking such defenses than the Rasenshuriken.
