Changing the male characters in the second scene data may cause Node Constraints to fail, so I will advise against it. If you insist on changing the male characters, you can try to re-activate/recreate the constraints on your own (the two constraints are kf_dan_entry -> MouthCavity, kf_dan_entry -> vagina_root)
