Ishi said that Issei peerage will be formed for old&new characters..

The initial members were all old characters and Ingvild is was one new character when she joined.. So. Probably he will add at least another NEW CHARACTER.

About Le Fay she can join Issei peerage(maybe as Rook) or be Rias New Bishop. She is in the Cup as Bishop, probably is the best pieces for her. Issei harem will live thousands of years. She can´t be the exception.

About the others 2.. Verrine is perfect to create RANDOM girls to add more pawns because probably is worthy of 8 pawns. Maybe the alpecca is worthy of the 8 pawns too and unlike verrine is not a devil but nothing confirms her in the harem yet but..

Anyway Ishi started calling her the mysterious girl like in Ingvild case in Shin 1 there is a chances that this happens again.
