That is some heavy speculation.

The reason the 9 bijuu can regenerate is because they are made from chakra with no physical bodies. The juubi however does have a physical body and was made from a humanoid and the tree, both of which stay dead once they die.

Hagoromo and Hamura don't have to die for the Juubi to stay dead, they exist as seperate entities from it.

Regardless if they actually battled the Juubi it was clear that together, they could not overpower it. Or fatally wound it, so they sealed it. Sure they were the only ones who could take on the Juubi but i wouldnt say that their power was close to what the Juubi had.

Hagoromo took all of the Juubis chakra as a whole. Before any kind of distribution to other people and before splitting them, so there wouldnt be much power loss if any.
