I've dropped the idea of having lacework in favor of other solution:
There was another angel in the seventh heaven, different in appearance from all the others, and of frightful mien. His height was so great, it would have taken five hundred years to cover a distance equal to it, and from the crown of his head to the soles of his feet he was studded with glaring eyes. "This one," said Metatron, addressing Moses, "is Samael, who takes the soul away from man."
Eyes. Living, translucent eyes, embedded into blades. I have totally no idea if I will be able to pull off the shader trick but I am gonna give it a try.
