You could also add in the Bandit archetype on top of thug or rake, since it trades different things. That would grant:
At 4th level, a bandit becomes fully practiced in the art of ambushing. When she acts in the surprise round, she can take a move action, standard action, and swift action during the surprise round, not just a move or standard action.
This ability replaces uncanny dodge.
Fearsome Strike (Ex)
At 8th level, a bandit can terrify an opponent with a single hit. A number of times per day equal to her Charisma modifier (minimum 1), when a bandit confirms a critical hit and deals sneak attack damage to an opponent, she can choose to make the opponent frightened for a number of rounds equal to her Charisma modifier (minimum 1). She cannot use this ability in conjunction with a critical feat.
This ability replaces uncanny dodge*.
It's kind of overkill, but a rogue 8 could trigger 3 demoralize attempts and a free frighten effect on a single attack by using Rake, Enforcer, Cornugon Smash, and getting a crit with Fearsome Strike. (with a bludgeoning nonlethal attack).
