[Ambush]-type feats in PF?

[Elric VIII]

I find myself with a few dice of SA on a Sanctified Slayer that is not geared toward TWF, archery, or stealth. I'm wondering what I can do with these that might be more useful than a few d6 damage. The rogue talents available to me do not provide much utility (bleeding attack, slow reactions, and slowing strike).

Are there any feats that let you replace SA damage with some form of debuff, similar to 3.5 [ambush] feats?

Best I got offhand is a 1 level dip into Rake Rogue (http://www.d20pfsrd.com/classes/core-classes/rogue/archetypes/paizo---rogue-archetypes/rake).
If you would deal Sneak damage you can skip a d6 to get a Free Intimidate check (something Inquisitors can be quite good at). Every extra d6 you trade in gives you a +5 Circumstance to the check.
