Not sure if Rias could become a Queen since we haven't seen a King downgrade to an Evil Piece.

Remove Asia, and use someone else.

Same with Xenovia use someone else. Bennia i don't think she'll leave Sona nor will Sona exchange servants.

Irina can't receive Evil Pieces cause if she does she becomes a Fallen Angel immediately. Le Fay seems to fit more into Bishop than Rook.

Kuroka is a Bishop Piece, she can't become other Pieces, plus i don't think Kuroka wants to become anyone servant. Fenrir is more loyal to Vali than Le Fay, Rassei is a familiar reincarnate him Asia will lose Rassei as a familiar. Kunou can't become one Ishibumi already said that. I can't say a thing about the female werewolf cause it's just your imagination.
