Human remain are human remains. Making a spectacle of them is not Christian, is not art nor is it respectful. Return them to their resting places and resist the strange urge to dig them up and play with them again, please, no matter how pretty you think they look.
Are you SURE you have an art degree? You seem to think that dirty Catholics adorned these skeletons with jewels in 2013 rather than several centuries ago. I would advise you to look closely at the beauty of the jewelry - truly magnificent designs - although somewhat unchanged from medieval designs. And the placement of the jewelry into the skeletons is amazingly intricate and delicate. Just think of the little hands of nuns placing them! Unless, of course, that makes you bilious. I’m made of stronger stuff.
