Neither you have disprove my theory. The fact is that Hinata(along with Hyūga clan) is descended from Hamura, so combining Hamura's chakra with her Byakugan resulting Tenseigan isn't impossible.

That said, it is possible that process would take more time with Hyūga than it would take with pure Ōtsutsuki. After all it took at least decades for Madara to awake Rinnegan.

Other possibility is that Hinata would need to channel Hamura's chakra directly into her Byakugan in order to awake Tenseigan.

So while not impossible for them, the process to awake Tenseigan would take more time for Hyūga than for Ōtsutsuki.

As for the topic, whetever Boruto gets Tenseigan or not depends if he gets Byakugan. And even if he do, the process could take even longer than it would take with Hinata.
