They have to be Hagoromo himself to regenerate his chakra, or have Hag's flesh implanted. Madara was a TTJ when Hag stated that and that makes a huge difference. They do have Six Paths Chakra, just like Madara had when he awakened his Rinnegan.. but it is not the exact same as Hagoromo's. The purity, strength, and volume are different than Hagoromo himself's. Otherwise they would be the same strength as Hagoromo himself.. in the war they each had half of his Chakra and lost it all by the end of their battle at VOTE2. It wasn't theirs to regenerate man.
