I would say that if there was a class that would benefit from that Warlock chassis, it would be the Psion/Mystic.If there's any class that's begging for a rework using the Warlock chassis, it's Monk. Scale unarmed attacks/Flurry of Blows to match the scaling of EB+AB. Move all of their "flavor abilities" into a menu of invocation-like options, and add a bunch more so you can make a Monk more like Goku or Aang or Ryu.
Most people probably wouldn't want monks "casting spells", so repurpose pact magic into offensive or defensive "ki abilities" that can be used 2-3 times per SR.
