I got it to work, sorta. I simply resized it to "0.1 0.1 0.1" via text editor and the .mis file. Then I went in and changed the visibility settings in ME. Otherwise it would look like this:

It looked pretty good, you'd have to go in and move/resize a few other pieces. But I got around the dissapearing part.

But then this happened.

It only happened by the window sill, and only when you faced a certain direction. Much like the dissapearing ghost brick glitch I often get.
I'm guessing that if you resized everything, moved it, and maybe turn terrain visibility inside of the interior on, it might work. Good Luck.
