Re: Can Madata make his own version of Bijuu PS?
For him to have that form of PS (or different but similar), he'd have to release the Juubi, stop being its Jinchuuriki, and seal it directly into his PS.
Although what Sasuke did was still different than what I thought. According to Kurama, Sasuke did the reverse of what Hagoromo did. Instead of seperating Kaguya's chakra from the Gedo Statue, Sasuke brought that chakra and it became one again (he used his PS as a replacement for the Gedo Statue so Kaguya didn't have any direct influence over the transformation/no Juubi emerged but still contained its chakra).
This actually makes me question whether the Bijuu themselves have to be sealed into Madara's PS since it would have to be a replacement for the Gedo.
