I really want to read this now. You have combined my two of my favorite things. Jane Austen and epic slash fanfiction. The only downside I see is that genderswap!P&P will no longer pass the Bechdel test, and we in fandom generally fail at writing stories that pass the Bechdel test. But I am always interested in changing a character's gender and seeing how the story would be different or how it would be the same but would be seen as different.
