The most magnificent part would be if he then issued his first papal decree to change the way the title Cardinal is used so they stop treating it like its a middle name. From that point on, he'll be ordering Cardinal Walter Kaspar, NOT "Walter Cardinal Kaspar".
It is very remotely possible that two men with the surname Burke might simultaneously serve as Cardinals of the Roman Catholic Church. In the 1950s, two brothers named Cicognani simultaneously served and were known respectively as Amleto Cardinal Cicognani and Gaetano Cardinal Cicognani. Amleto served as Secretary of State and Gaetano served as Prefect of the Apostolic Signatura (essentially chief justice of the Vatican's supreme court, the office currently held by Raymond Cardinal Burke). Those were and are two of the most important offices in the Vatican.
Personally, of course, I would prefer that after due, ummm inquiry, Pope Leo XIV might order Walter Cardinal Kasper and a number of similar miscreants, burned at the stake. Alas, as Cicero might observe: O Tempora, O Mores! We no longer exact the full measure of justice even at the Vatican.
