Sorry to hear about the surgery, but it gives ya more time to put together your act.
I concur with playing up yer female wiles - nothing distracts and disturbs a male gambler more than a glimpse of a bit of unexpected territory we might dream of exploring!! Throws us right off our game, it does, as the brain loses all its blood flow... Can't help but be to yer advantage
Some ideas for some games that might be part of a GaOP skillset: - and have been used by swindlers for decades (so fits with yer pickpocket image)
Fast and Loose
Pea and Shell Game
Dice of some kind
Cards? (think 3 card monte)
Now these require some practice to get right, and can be purchased at a magic shop. Of course, if ye don't get them right, ye can always let them know a flintlock pistol is under the table aimed properly.
