I don't think Rias should be promoted at the moment, you can't give the same promotions to Issei. After all, Rias doesn't have Issei's achievements. You can't put it right now, maybe after Issei's investment as Maou. This promotion is too little for Issei's achievements. I think that only those who currently hold low ranks will be promoted.
