I thought the same thing. I went back to the first thing I ever put here, and it has my current title on it, and I thought, "that wasn't written by 'Monsignor Kyle', it was written by 'Newbie Kyle'!"
I realize that from a technical point of view, it's probably not possible to have a historically accurate title, but that would be fun.
Update, just to be clear, I like the change. I'd probably add an "acronym" tag around the title, though, like so:
<ACRONYM TITLE="level 18">Monsignor</ACRONYM>
This way someone can hover over the title and find out the (more comprehensible) number associated with the name, but it stays out of the way of anyone who's not interested or already knows.
