I sort of went the other way when setting up a FFG-fied version of "Dawn of Defiance". One of the episodes leans heavily on a gambling tournament on Bespin, and I've never been overly-happy with FFG's take on gambling in Star Wars, so we went ahead and created a new skill, called (imaginatively) "Gambling".
We wanted the ability for characters to increase their skill at the sabacc table, and not just rely on attributes. We haven't actually played that one, yet, but they've actually used the skill in our other games, and it seems to work pretty well.
My ultimate plan is to actually create a "Gambler" specialty, including a custom talent tree, so that a player could specifically mimic gambling characters of past stories (a "Maverick" type, for example).
