While I will wait to see the completed project to pass final judgement, I am not sure these new panels are going to substantially change the look of the tower for most viewpoints. The crown's glass is still going to look very different from the rest of the tower, which I felt was the whole problem, not the mechanical looking backing.
I liked the texture of the old material, and if it was painted blueish-gray like the rest of the glass and didn't have the sheet metal vents it would have looked great.
