No, they don't work on any other fictional universe, unless it's a D&D novel or something similar.
Very few characters can really fit the inscriptions, and those are usually the ones created with the concept 'I'm a force of good with a stick on my ass' or 'Hot Damn, I'm evil for the heck of it', and these are NOT many.
Lelouch isn't Chaotic Neutral for the simple reason he doesn't want anarchy and to overthrow lawful constructs.
He just doesn't like the current one, and fights to replace it with what he thinks is better (for his sister yadda yadda).
Not exactly chaotic.
