Was asked a question last night regarding how Lotus Geisha and Dawnflower Dervish archetypes interact with their respective Enrapturing Performance and Battle Dance abilities, I would say they don't do anything together based on one line from each:
Battle dancing is treated as bardic performance for the purposes of feats, abilities, and effects that affect bardic performance
A lotus geisha cannot have a bardic performance and an enrapturing performance in effect at the same time.
