Here is my guess

First against most of the other ideas:

I dont think that either Sona, Raiser or Rias will hand over their pieces, especially not against nothing but unused pieces.

Rias loves Ise, but is a professional she won't simply hand over her peerage or even single members, not even for Ise.

Sona won't hand over any of her pieces, as she has trained them with effort and like Rias is a professional who won't give her servants away, even if they have a crush on Ise.

Raiser won't hand over any pieces that are part of his harem to Ise, even if they are buddies now, after he already lost Rias to him.

King - Ise

Queen - Rias --> As his legal Wife and the woman by his side, eventuelly trying to rival grayfia as the ultimate queen

Bishop - Ravel --> obvious

Bishop - Valerie --> Ise will take Valerie with the intention of trade, for Gasper

Bishop - Asia --> Rias won't just hand over Asia, but she will trade with Ise and get the grail Valerie as her bishop, Gasper and Valier together in Rias peerage (Only piece Rias will hand over)

Knight - Grim Reaper (possibly 2 pieces)--> of now unknown, will be met in later volumes when the conflict with hades comes back up

Knight

Rock - possibly sprecte dragon (1 Piece), which is about to be born

Rock

Pawn - Mil-tan (2 pieces) --> hell why not? would love to see it, posesses enough strength ( I hope that she is unknown to herself one of the remaining longius user, while it's very very very very unlikely/ won't happen -.-)

Pawn - unknown sacred beast (3-6 pieces) --> Sirzechs is the only one to have turned a sacred beast into his servant, i think Ise will be the second (possibly second rock instead of pawn)

--> Rest unknown,

- possibly one of the remaining longius that have yet to appear

- Crom Cruach ( unlikely, perhaps wishes to follow Ise to see where Dragons are heading, as he is the one thats involved in change)

- Tiamat (also unlikely, as she has no reason like Tannin, who did it for survival )

- more possibly other species like youkai, werewolf or western monster (Vampire not so much)

Ophis --> God and mascot character, wont be part

Kuroka --> Does not want to become a servant

Le Fay --> Contract Magician, won't become servant

Irina --> Angel, won't become devil

Kuno --> Author said isn't going to happen

Kyome Abe --> Monster Tamer, not a sutible fighter, Ise hasn't really shown interest in her

Kiryuu --> support character for Chirch Trio, hasn't shown interesst in Ise, very unlikely

Jeanne --> No, just because she is a woman doesn't mean she joins them, she is evil and hated, has shown no interesst in Ise
