If anything I think the set bonus with the enchanted crown will go with other enchanted items. Since that stuff is all garbage, it's totally pointless to get the enchanted crown unless you are just hoping that they will change enchanted stats (which I hope they do). Personally I am getting the enchanted crown simply because I am an insane collector of mage gear, but I'm gonna try to level up another chanracter so I can get a more useful crown (like customized) as well, which I would be far more likely to use.
