Thanks for the update on Figure size this then looks perfect for layout and trains, just a lot of work to paint them.
As for the Hogwart's Castle with the LED lights that was posted above on e-bay. Yes looks like the one from the series that I got the Castle was sold out before I could get it. Think it was around Christmas they were with the Christmas village houses etc,. Was around 30-50 $ as I recall at the time? Castle on e-bay below;

As for cutting out windows in the 3D Puzzle there are hundreds of them not sure how well that would work with the puzzle pieces. I would think it would look better just building it and lighting it with light in front.
The puzzle looks really good.
