^Except Sasuke got Rinnegan through Hagoromo's chakra. Hashirama's cells may have strenghten it, but it was still Hagoromo that gave Sasuke Rinnegan.

Also, I don't think it was ever stated in the movie or Retsu no Sho that "flesh" of Ōtsutsuki was required in order to awake Tenseigan. Both Byakugan and Tenseigan articles states that Ōtsutsuki chakra combined with Hyūga Byakugan awakes Tenseigan, and Hinata has Hamura's chakra, so that should be enough, even though it may take longer for Hyūga to awake Tenseigan than pure Ōtsutsuki(and even then it took Toneri some time to awake it, if I remember correctly).
