Hagoromo and Hamura were half human, they are not genetically pure. Half their geneology didnt even have the ability to create chakra. Their chakra is not identicle to Kaguya's and they didnt receive her full powers/abilities.

They still didnt need to become host of her or her chakra to attain SPS. No one sought their bodies to attain chakra like the Juubi and recreating Hagoromo's chakra doesnt give the user Juubi qualities. Hagrormo's chakra alone isnt enough to obtain SPS.
