I don't think the geomSwitch changes out the children with the parent. Mason made a version that switched out the chest, but it didn't take the collars or the neck with it as far as I know. You could create an extra-OBJ call in the cr2 for the hands, but that only works in Poser4.03 I hear. Prior versions of Poser would toss out the extra OBJ call on save.
