Eclipse Defense (Starfinder #35: Merchants of the Void pg. 53) is a KAC+8 like most other combat maneuvers. So can a solarian take Improved Combat Maneuver(ICM): Eclipse Defense for a +4 to use this revelation? Would the +4 bonus from the ICM stack with +4 when Graviton attuned for a +8, both are unnamed bonuses?
