We do have different dances you can learn, and buy throughout the game, maybe a system were you can chop up and reassemble various dances into a new one to make a dance routine would be in order. By chop up i mean mix and match certain dance steps or movements within a dance step and combine it with other ones to make new dances but that are only usable during Dance Performance for the Dancer job that way it doesn't ruin the prestige of buying new emote dances or earning them through other reward systems.
