Not what he asked. He knows whose layout it is. He is looking for modeling opinions, not permission. "It's your layout" is never helpful.
Now, to address the question: holy cow, that's way too big. Think about it. It would look, to use a technical modeling term, stupid.
1:32 is #1 scale (as in the big MTH line), not #0 (the proper "O gauge" term - it's a zero, not an "O") scale.
