Maybe have you already read the memorandum of the Lehman brothers (Augustin
and Joseph who converted to the Catholic Church and became priests) presented at the Vatican council in 1870. If you read French, it is intitled La Cause Perdue des Restes d'Israel [The lost cause of the remains of Israel]. It is a document approved by the late Pope Pius IX inviting the Jews to convert and join the Catholic Church, not exactly in the sense presented by the Vatican Council II. Unfortunately, I only have it in French.
