I say almost up there because I really would highly doubt they'd include titles from past limited time events because that wouldn't be fair to people who didn't start playing on day 1 in Japan.
Titles already have a value, they cost a certain amount of gil to change back to the title at the adventuring bards. This would be a somewhat easy way to implement a system that involved weighted titles and a total amount of points required to achieve a rank.
