This reminds me of a character I had on another server, a Cleric, who was young. I played him so that his "effective" healing level was near his age; I did not want him at 18Y 2M 14D being able to resurrect. :P For a while, I had DM's bump me back down as needed to keep that in check as I would level.
However, they also had a server rule where you had to be within, oh, 5 levels or so, of your party members to party, and I was getting left behind as my friends progressed. So I came up with the bright idea of gaining my levels...but not filling any of the spell slots over level 4 spells. Now, I could do nothing about spell DC's, damage dealt, etc, since my character level was 20, but I could affect how much Clerical "power" my PC had by that simple control. It was not until a couple of personal quests that I allowed him to slowly gain power (i.e. additional spell levels).
Remembering that, and looking at your situation (similar), I am wondering, if for your suggestion, it would be easier to script that you can actually request to reduce your levels, without affecting your notoriety score? :-/ I would think so, as it seems your notoriety system should be independent of hard-coded Bioware XP.
