Wine bottle box cars

[ttrigg]

Throw in a pic or two and I'm sure someone can suggest an idea or two.  Without seeing what we are talking about, I would say "throw some trucks and couplers under it and have a go."  (That being said, I have been know to let my aligator mouth overload my humming bird tush.)

I'm not a large scaler but my wife brought home from Home Depot poinsettias in two Chianti Classico wine bottle pine boxes. These are 13 1/8 in. long, 4 3/8 in. wide and 4 1/8 in. high. Of course my first thought was G gauge cars. Im not up on the best scale for these; I know that scales run from 20 point something to 1:32. So I need help in deciding what scale and what kind of cars. I'm thinking one would be a caboose. Any ideas on kitbashing these? Also, if you can think of any ideas, you might want to run to Home Depot and see if your store has any of these. They come with a plastic liner which I assume is in case someone dropped the cheer and it broke.
