Kisuke will probably go to SS when he's finished analyzing the medallion in Hueco Mundo, and possibly also gathered the remaining Arrancars, or whatever he's planning.

In addition, Shunsui should call in Tessai and Hachi before the next invasion. They are the former captain and lieutenant of the Kidô Corps, after all, and Hachi seem to have greatly improved his Kidô skills during these 100 years after the hollowfication incident.

The 2 of them alone are very powerful, and with the Kidô Corps in addition, they could greatly make up for holding back the remaining Bankais and fight the Stern Ritters evenly (I hope).
