do Ты think luna and ron would make a good couple?

No, I think that Ron should be with Hermione, and Luna should be with Neville. Ron and Luna never did seem to get along that well.

Yes!!!! Theyre 2 of my favourite characters, so them together would be awsum! I dont no how 2 choose, tho, cos hermiones 1 of my fave characters 2. But i like neville, and i reckon lunas good for him

No. Of course not. They are clearly different from each other.

Yes, they are perfectly awesome for each other. Luna would help Ron feel relaxed and calm. When he's with Hermione, they are constantly fighting!
Here's some evidence from the book:

"You know, she's grown on me, Luna," Ron said, as they set off for the Great Hall. "I know she's insane, but in a good way."

"Anyway, good luck, Ronald!" -Luna Lovegood

YES!

No, they are so different from each other. But not in a good way. Differences can make a relationship special, but not in this case.

I really can't imagine them working as a couple. I can't see Ron accepting Luna's quirks enough.

No, because Ron and Luna are nothing alike and RON MARRIES HERMIONE. It is plain to see that Ron and Luna are not a good couple, I mean look at the Фильмы and Книги it is so plain to see that Ron and Hermione go together perfectly NOT Ron and Luna.
