How Harry Potter Should Have Ended?

In the wake of JK Rowling's recent revelations that she felt she might have made a mistake, and that Harry and Hermione were better suited than Ron and Hermione, I find myself agreeing wholeheartedly. Like most of my other fan-fics, this is an experiment of sorts. The goal is to see if Rowling could have "fixed" the romantic arcs in DH without disrupting the entire series.
