Chiyo would participate of course. It is actually relatively easier for her to unlock the first of the sixth light charka than most, because her charka is naturally overactive mostly due to her personality. Despite not yet unlocking a shadow charka, she "knows" the mediation ability (assuming one would normally need to be on the shadow side of the charka to use it properly ^^). Because of all of this, her charka would open randomly getting her an uncontrollable burst of power, albeit, momentarily, usually when fighting or under stress or excitement. She already asked Berrod for help on this.
