Luna and Harry, please.Yes, the Muggle world is a good idea, in my mind. Perhaps we may start a few months after the final battle and have Hermione convince Harry to clean up his remaining link with his relatives after he's been feeling lost as to where his life should go? And since both of their relationship with the two youngest Weasley didn't work and they grey close to Luna, the two blonds could meet that way later on.

Works for me.

We could suggest that Luna wants more independence from her father and may consider getting a room someplace with Hermione while they consider what to do after the war. Harry reconciling with Dudley and everyone would be good too, Dudley needs that development. In terms of post-war, we'll need some kind of conflict or glue to keep them together. I'm not sure if we want to focus on personal bonds between the various characters or cook up another enemy, be it someone evil or possibly some kind of external threat to the wizarding world like someone threatening to reveal everything to muggles, or something.

In terms of what Harry would do after the war, I see him wanting to teach more than become an Auror. And I could see Luna wanting to continue the Quibbler but also find her own voice through either art or prose.
