Asura and Transmigrants inherited the Physical and Senjutsu from Hag, while Indra and Transmigrants inherited the Spiritual and Dojutsu from Hag. Tailed Beast is not meant to be inherited to either of them, it's meant to be free. Even if it is, it'll be inherited by Asura and Transmigrants due to him being the inheritor of Ninshu, not the inheritor of Physical.
