I have my doubts that the architectural change was simply happenstance. I think the people who control the money make the decisions on architecture just as they did with the changes in the mass itself. From the birth of the church the Catholic Monarchies controlled the issuance of money, the relevant geographical cultures and military for defense of the church. All Roman Catholic Monarchies were abolished after WW2 by the Roosevelt administration. It is a well know fact that FDR was a central banker.
When critical thinking is applied to our history beginning with the end of the civil war, we see the birth of the American central bank take place. The central bank needs to knock out the Monarchies in order for their families to rule the world, hence, New World Order is opposed to the Old Roman Catholic Order.
The Novus Ordus mass is really New World Order run by the American central bank. They are also known historically as a den of vipers, and are Christ Killers, and, enemies of our church. The modern architecture and Novus Ordus mass are from the same root and Catholics need to know the true history of our church. The central bankers are the ones who control all religions using the cover of the federal government and through tax scheme exemptions.
The Central Banks were definiitely the enablers of the reign of Liberty Christopher Ferrara writes against in his book "Liberty the God that Failed." It is also true that these banks, beginning with the Bank of England in aftermath of the Glorious Revolution of 1688 (founded in 1694, in fact: www.bbc.co.uk ) have gone hand in hand with the rise of Revolutionary Republics. It is certainly no coincidence that the Federal Reserve's institution occured just prior to our entry in to WWI and the War Socialism described by Jonah Goldberg is his book "Liberal Fascism: The Secret History of the American Left, from Mussolini to the Politics of Meaning."
That said, it has to be noted that both arise from a similar ideology and metaphyical worldview that, in many ways, amounts to a religion. This is the aspect of Modern Philosophy's power that neither the investigate what has been called "the great conspiracy" in some circles, or their detractors, recognize. Ferrara's contribution to our understanding of the phenomena is that he, along with a few others and more than any author I've read so far, reaches not only into the history, but also the Philosophical threads that lead from Descarte, whose "Cogito" rendered men into ghosts unsure of external existance, through Hobbes and Locke to what we have today.
