Well, I don't know of any metamagic or metapsionic feats that would give this ability, so we'd have to probably make the feature from scratch. Now, a metamagic feat that could allow effects to bypass force effects would probably be very costly, possibly as much as Quicken Spell. That would translate to as much as 8 PP for the augment, and I think 6-8 PP would be appropriate. Maybe split the difference and go with 7 PP?
