What about Pope Suburban? The Holy See could sell naming rights to Chevrolet.
My bet the new pope will be from South America—Brazil or Argentina.
What about Pope Lexis the Ist.
Wide trac Pontiac II.
Pope Tesla Electri?
Likewise, since the next pope will probably continue the practice of "tweeting," he won't take the name Sylvester (that name has been used--Sylvester I supposedly cured the Emperor Constantine of leprosy, the rationale for the fictitious "Donation of Constantine")...would lend itself to too many jokes about Tweety and Sylvester.
The early popes kept their original names--a lot of the early ones have Greek names. There don't seem to be any papal names of Germanic origin (Robert, Albert, Edward, Frederick, etc.). There was a short-lived Pope Conon--maybe a Pope Conon II would be just the one to take on the barbarians of today.
There were two popes named Paschal (the first elected in 817, the second in 1099)--that might be an appropriate name if the election takes place near Easter.
Stephen, Nicholas, and Adrian are some other names which haven't been used in a long time.
After a string of popes named "Pius" (7 out of 11 in one stretch), the most recent popes have shown more variety with the exception of JPII taking the name of the pope who died after only a month in office.
