whoops. My bad.But Viking Bastard was working-off Nivenus's proposal.

I actually think there should be 10 alignments: the told 9 alignments plus 4e's Unaligned.
Why you ask? Because Unaligned really covers different ground then True Neutral does. Neutral, as it existed in editions prior to 4e, always came in basically two flavors: characters who were actively neutral and seeking to avoid being "overly" good, evil, lawful, or chaotic, and those who simply didn't care.
The "didn't care" flavor meshes well with the Unaligned alignment, while True Neutral doesn't really.
Also, I'd favor simplifying some of the names. Good and Evil can become the new names for Neutral Good and Neutral Evil, indicating that characters of those alignments aren't actively trying to balance law and chaos most of the time, they're just fully devoted to serve good or evil.
Similarly, I'd rename Lawful Neutral and Chaotic Neutral to simply Lawful and Chaotic, which I think would solve some of the "Lawful Stupid" and "Chaotic Stupid" problems of prior editions, so that players of those alignments don't feel like they have to constantly go back and forth between being both good and evil and instead just focusing on a devotion to order or chaos.
P.S. Foolish Mortal? I think you just described 4e's 5-track system (LG-G-U-E-CE)
