Perceisely. There must be something special about Kawaki that makes his body superior to these other shinobi. My suspicion is the Shinobi-Ware, which has only been developed recently and seems to be core to Kara current activities.

I think the Shinobi-Ware is going to be what allows Isshiki to inhabit a human, without it, its possible the chakra would be too much. Because honestly, if Isshiki has more chakra than Naruto, than he has more chakra than Hashirama and the Third Raikage as well. Also, Madara's large chakra volumes were either because of his reanimation or because of his Ten-Tails' Jinchuriki status. Under normal circumstances his chakra isn't larger than Naruto's.
