I've written a George/Luna ficlet if anyone's interested.
George isn't coping very well in the months after the last battle and takes to walking in the countryside around The Burrow, where he comes across Luna Lovegood fishing for Freshwater Plimpies at Bottom Bridge.

It's after the war and Luna and Neville are leading secret lives. Whats going on? What Death Eaters? Can George help Luna and let her know how he feels?
