the issue of Hinatas clan being in the picture in that regard was handled a long time ago. It wouldn't matter any ways because Hinata would either quit her clan outright, or Naruto would change the clan. So the clans choice in the matter would be irrelevant.
The real issue for Hinata is can she let go.
I would wager that Kishimoto sensei for Hinata is heading for a similar dialogue to the Promise of a lifetime for Hinata to Naruto. A speech where she says perhaps almost line for line " you love Sakura don't you? I can tell, I hope you and Sakura will always be happy and I promise Ill always be there for you.
that's the next logical step for Hinata can she let go of that which she loves/crushes on.
catsi if that happens the entire NH fandom will explode into endless rage, it will be like meltdown or a nuclear bomb going off. They will be like "I hate you Kishimoto" "Worst manga ever" "How dare he do that to Hinata" yeah I can see the kitten storm in the horizon if that will actually happens.
