This is pretty awesome, indeed. Will the CEP weapons also be able to be targeted by spell buffs?
If they aren't already I did a fix for CEP weapons not taking spell enhancements for another server a couple months back from scratch. Ravenloft uses it's own custom scripts but if they want to look at it so they can figure out what needs changing at what points and do their own edits I can send it through.
By default in nwn there's like two different scripts that the base items needed to be added to, to bypass the safe item Property scripts and add them to the list of permittable weapons, on top of editing the spell scripts themselves to allow it because of (I suspect).
My scripting was pretty rough though, but I tried editing different aspects of it when I was done to try simplify it and it kept breaking, so it seemed like it required every point at which I edited it.
But my maul is able to be enchanted IG in Ravenloft so I'm fairly sure they already have the CEP weapon stuff sorted.
