Its not just the chakra, If Toneri was to gift Hinata or Hanabi his chakra they would surely awaken their own Tenseigan.. but they would not keep Toneri's chakra they would then awaken their own Six Paths Chakra to go along with the Tenseigan. Plot is the only reason they don't have Tenseigan honestly.
