You cannot regenerate another beings chakra without having their flesh in your body. They can regenerate their own Six Paths chakra, but not Hagoromo's. His is more vast and more powerful than theirs and that's undoubtable. That is why they were at their peak when they fought Kaguya and at VotE2. They literaly exhausted all the chakra they had at the end of their fight and that includes the chakra Hagoromo lent them. Its like the Shinobi alliance having Kurama's chakra.. once they used it all up it was GONE and they cannot make more since it is not theirs. They went back to their less powerful and less plentiful normal chakra. Dan also sent his chakra to Tsunade, do you think she can regenerate his chakra once she uses it up? no because she does not have his flesh to do so.
