It is not very difficult to get large cheeseboxes, if you ask at the right shops. Not nessessarely at the next El Cheop supermarket down the road.
And of course, you can always build your own box, if you really need one.
Found this cheesebox layout at Railexpo in France some years ago. 2008 I believe.
Bob arranged the well known and popular Ratatouille charakters around a cheese theme. That makes perfectly sense. What else should mice transport on a railway? A very charming and amusing little layout. I doubt, that it will draw any newcomers into the modelrairoad hobby. But it will make many onlookers happy for a moment. And it proofs, that some modellers actually have humor and dare to show it.
