 ::: By way of comparison, there's an article Coronation of the British monarch and List of coronations of British monarchs, the latter giving dates for the coronations of queens as well as kings.  Perhaps an article Coronation of the Holy Roman Emperor could be created, which would include both details of the coronation itself , and a list of coronations, dates, officiants, and whether they were solitary or with an Empress or of an Empress alone.  The Imperial coronation was a remarkably infrequent event; I count only twenty times that an Emperor was crowned from 962 to 1530  only sixteen times by a Pope.
