Some possibly controversial thoughts about a dancer addition

[Singularity]

All jobs so far, while allowing you to integrate renovations (DRG comes to mind) were largely about tapping into the abilities and skills already existing within your Soul Crystal and abiding by your mentor chara's route. That leaves not as much room for racial differences, and again I should hope they won't go overboard with the differences based on gender.

Well, from a lore perspective, the job crystals (MCH excepted) all talk about the "myriad deeds of <job>s from ages past", so your dancer crystal would presumably have been owned by many dancers before you and thus contain a wide range of dance motions.

Because let's face it, going by this game's track record it's almost certain that male charas will get shafted, and I just don't trust them to pull a BRD again

That's a genuine concern, but it's a separate issue from merely having different motions. Neither gender deserves to get animations of lesser quality, nor to have motions intended exclusively for the other one shoehorned into its animation set.
