No, Jon. The Unaltered Augsburg Confession will not be permitted. One difference between Anglicans and Lutherans is that the Lutheran Patrimony is largely theological where the Anglican patrimony is not.
The Catholic Church has made it crystal clear that all entering an Ordinariate must want to be fully Roman Catholic in every way. Those wanting to bring the insignts of the English (or Lutheran) Reformation into the Catholic Church to reform it will not be welcome; and that is as it should - and must be!
For Lutherans, what is left to bring with them as their Patrimony is musical (Bach, Buxtehude, Schutz, et al.) and cultural. The Lutheran Music and non-theological Culture of Germany and Scandanavia is already shared with Roman Catholics or German and Scandanavian Heritage, and the music of Bach, and Luther’s “A Mighty Fortress is our God” for instance is already being performed in Roman Catholic Churches.
The reason for Lutherans to return to the Catholic Church is only because they want to heal the wounds unnecessarily inflicted on Holy Mother Church in the 16th Century and make Christ’s prayer that all his followers would be one as He and the Father are one - in one Church, under leadership of Christ and his earthly Vicar, the Successor of St. Peter a lived reality once more. Lutherans entering the Catholic Church are doing so because it is not only the right thing to do, but because it is the only right thing to do. Ut Unum Sint!
