Some of the people behind it are Catholic.Check out this: “A New New Testament”, published 2013, by some major denominational leaders who voted on 10 books to add to the “traditional” 27.
The Catholic Magisterium identified, but God was the creator, of the New Testament canon, which the above version opposes. It was the visible human agency through which God publicly communicated His will that: Books will be added to the existing scriptures. These specific 27 books were deemed to be inspired. Other books that were considered then, were deemed to be excluded from the New Testament. The New Testament canon was then CLOSED. The Magisterium continues to maintain the 27 book canon today.
All of these were decisions, not evolutions, made not by Christians in general, but by a single, specific identifiable part of the Church. God didn’t need any Magisterium, but He chose to use this means. The Magisterium’s canon likely did not represent the majority of Christians or the majority of scholars at that time. At present it’s likely a majority of scholars doesn’t accept the Magisterium’s 27 book canon, and in the future a majority of Christians won’t accept it. In the future it will be much harder for Christians to defend the traditional 27 book canon, if they reject the authority of the single, identifiable, currently visible human agency that closed the canon, and keeps it closed.
Unfortunately the people behind “A New New Testament” have far more media and academic clout than the Mormons ever had, when they tried to add books. In the future, those who hold to the traditional 27 will be regarded as quaint, like people today who believe the Earth is flat, based on the Bible. In the future, I predict Protestants will follow whatever canon their denomination or congregation chooses, and there will be many canons. Protestants who are unwilling to break with the traditional 27 books, will take a good, hard look at joining with the single human agency that communicated that canon in the first place, and keeps it closed today.

That said, I am sure that communions such as the Catholic Church and the LCMS will stay well away from this officially. While I am a strong proponent of ecumenism, I’m curious as to why you believe that communions such as the LCMS would be drawn to Rome simply because other communions would take on this new canon.
