Well, no one has answered in another way yet, so may as well make my comment an answer as DavRob60 suggests. 'Tis popular anyway...
1) Both questions explicitly mention trying to fill out a Wookiepedia page, but without wanting to do any legwork of their own (hence asking here).
2) When you mouse-over the downvote button, it does say "This question does not show any research effort", so dowvoting it into oblivion certainly seems to be the right thing to do.
3) As mentioned in the question, they do otherwise seem to be on-topic.
So I'd say, do nothing. The community will handle them the way that these two questions have been handled.
Additionally, as referenced here: Auto-deleting old, unanswered zero-score questions after a year?
We already auto-remove negatively voted unanswered old questions
automatically after 30 days, network wide, with no human intervention
So as long as no one answers those questions, they really would be handled entirely by the community.
