Seems to me they should already be out. Well in case no thoughts on them here are my thoughts, Emerald, ruby and diamond Weapons from FFVII give them free roam which means they can spawn in every possible map area. give them rank of SS.
Also while on teh subject of hunts i think you could also add Savage either weekly or monthly hunts which would be hunts that you accept from the board but would require a full party to complete
