So then, you can cast multiple copies of the same spell targeting the same object, as long as there's always only one copy of each named object attached to the object? Or is it illegal to target an object with a spell if doing so would prevent the spell resolution step? Is the casting and targeting illegal? Or is it just the resolving?
Or is it just a special exception for equipment? If your lash of hellfire gets disabled, could you do the same thing and replace it with another lash of hellfire that isn't disabled? Could you replace a mage wand with another mage wand?
Or is this a special exception for equipment objects that give their mage an armor trait?
Also, I forget what happens when you replace a mage wand with another wand. Does the attached spell get discarded, or does it also go back to your spellbook? I couldn't find this in the rules supplement.
