You need abilities to reflect on the general audacity of the rogue. Hell, maybe give them the ability to Charm a person (what? Rogues always make amazing flirts, so...), with some bonuses if used against a flatfooted creature (so you can pull the classic Bugs Bunny move if you really want to...)
Also, they should the get the Swashbuckler's Seduction class feature. I would play a Rogue just to get that ability. I love it that much. (Essentially, you can use Bluff to get information out of someone, taking pretty much the whole night if you roll low, but taking only a few rounds if you roll high enough. Yes, they do kiss and tell, thank you very much.)
Basically, all I'm saying is that your average Rogue should be a lady-killer (or female equivalent) on top of being a killer.
Also, some ability to nick pocket change off someone would be nice (Bards get Perform, NPCs get Profession, you get Sleight of Hand; yep, it stereotypes you a bit, but you are a sexy sexy criminal! What more could you want?)
