I can't remember how exactly the cube recipes works anymore, but would it be plausible to see if the cube recipe can check if the item is ethereal, if so, remove 50% defense on fixing durability? I think that'd stop the bug from happening but I don't think you can remove def% in the cube if I recall, that, or it applies the defense after the recipe.
