Interesting thought. I think the class might be complex enough as is, but maybe just a feature of Tools of The Trade that allows you to hide the body quickly rather than making an extra attack.
Also, I cannibalized some features, combined some, simplified some of the text, and made Tools of The Trade more versatile, since it's so situational. You can hide or intimidate now, in addition to the attack option. All the weird ribbon-like features have been either combined or deleted, I think, as well.
Other than the extra use choices for ToTT, the class has the same number of features as the rogue, right now.
