Good, but not Holy (weapon enchantments)

[Calybos1]

Does anyone know of a PFS-legal way to make a weapon good--i.e., permanently good--without going for the full-bore +2d6, negative-level Holy ability?

Sure, Bless Weapon and Align Weapon spells can confer the property for awhile... but I'm looking for an effect or item that permanently turns the weapon into a Good-aligned one.

Bane(Outsider, Evil) is the closest your going to get. Or just have a +5 weapon, if all your looking to do is bypass alignment based DR.

Edit: Or the negating weapon enhancement. Of course, these are all priced as +2 enhancements (or more), the same as holy. So, you're not gaining anything.
