I've read some great modern adaptations by orchidvines
"Personally, I'd Rather Lick Sand" - modern P&P
"Ancient History Comes With a Helmet, Right?" - modern persuasion
both awesome, and hilarious!
Also Queen Eleni wrote a 'much ado about nothing' set in regency england. Bea reads Sense and Sensibility at one point. XD
I've got an ff account myself, though I deleted all my old stuff: J.Wilde
and I've got some original works posted on fictionpress
