replacement

I have been steaming bread with the cup and pan method but every time I do, I cover the door window on my LG range with a large towel. Which takes time. Which lets heat out.

I checked with LG and they don't make a replacement door with no window.

Has anyone replaced the inner glass in an LG or other gas range with metal? Thinking if I got the exact dimensions on the inner glass, I could salvage an old metal oven door and have it cut to git. Then replace the inner glass with the metal.
