Also vivisectionist alchemist, sanctified slayer inquisitor, cult leader warpriest, sandman bard, a druid with the crocodile domain (ideally a skinshaper or urban druid) and enigma mesmerist. If the only casting wanted is to sneak around then a ninja or a stygian slayer might work.
The vivisectionist alchemist has full sneak attack and relatively sneaky 'spellcasting' so might be the best of those for the purpose.
