A common theme can be the redemption or new start for Harry. In these fics, Ginny might be bashed as a way to show that she wasn't the right fit for Harry. Harry's relationship with Daphne then becomes a way for him to have a fresh start, away from the somewhat tumultuous relationship with Ginny in the original series.

There's 'A Different Path for Harry' which is a 'harry x daphne ginny bashing fanfic'. In this fic, the author creates a scenario where Harry and Daphne end up together.
