After Genra all the old moveset of DoA would be finally here (considering how Kasumi Alpha e Shiden are basically already in the roster through Alpha-152, Phase 4 and Hayate). Also, with Phase 4 being the representative of the cloning project of Kasumi that has a key role in the plot, with Raidou being an half mimic character for the ninja and Honoka being a completely mimic character for the rest of the roster, I really think that at this point all the options for recycling movesets should be already ended.
By the way it's also true that Genra had very few moves, part of them singular ones but other got from Spartan: contrarily to Bankotsubo and Raidou, he would need to get a major restyling and improvement of his moveset under the external side before than about the properties of it.
Anyway for the DLC characters we can easily expect only female characters, with the only unlikely exception made from Donovan if TN already created a real in-game model for him. If people really wish for Genra and not only his moveset maybe they should expect DoA6, otherwise is pretty possible that we could end to get a female substitute for him or Donovan inheriting his fighting style.
