Of course, the idea above is just a sketch. In line with the idea that "themes" are feat packages and "backgrounds" are skill packages, what I'm proposing above would be to create a handful of rogue "schemes" that strongly flavor the class and generate nice little bundles of what were formerly called rogue talents.
They could, but probably shouldn't, overlap with backgrounds. A rogue "scheme" should open the door to new class abilities, not merely skills.
You wouldn't need very many to make the rogue a very interesting class. If you pick two, then six "schemes" gives you 15 flavors of rogue.
Some other schemes along these lines could be:
Street Fighter
You grew up fighting for your daily bread, and became quite good at it.
Skills: Balance, Intimidate, Knowledge: Local, Perform: +2
Talent ideas: trade sneak attack dice for special effects, defensive roll, heal or buff with a swig of alcohol...
Arcane Addict
You have just enough talent for magic to make your life miserable.
Skills: Decipher Script, Disable Device, Knowledge: Arcana, Use Magic Device
Talent ideas: open up UMD uses (or grant them if the skill isn't in the game); learn a very small number of spells as per the PF talents; arcane strike
Cat Burglar
You get as big a thrill breaking into the penthouse as you do out of stealing its jewels.
Skills: Acrobatics, Balance, Climb, Jump
Talent ideas: Like the T-A of old, open up new abilities such as pole vaulting and tightrope walking based on the acrobatics skill; ignore difficult terrain; lots of possibilities here imitating parkour racers and Jackie Chan.
