I'll (kind of) agree with you to a point. I think that anyone descending from a subject of the kingdom at the time of its overthrow should automatically have the option of becoming a citizen of the new nation. And note nothing says it has to be a kingdom once again. The current citizens could opt for a representative democracy. Now as a practical point my proposal wold cover every living person who has Hawaiian blood and they would make up 99 percent of the eligible people.
