I don't think we can do that at a price we are willing to pay. I don't think the CoS were lying, or particularly exaggerating, when they told us that wearing the crown changes you. I wouldn't be surprised if it was one of those costs you can't be immune if you want the benefits of an item/effect.It might be possible, but for me at least it'd be unsatisfying not to personally subdue the court and bind them to our will.
We might be able to use it as a focus for a curse or something if we want to be more directly involved in screwing them over though.
