The Millennium Falcon is impossible to make. The inside physical dimensions are much larger than the outside dimensions. Ever notice how big the different rooms are inside during the various scenes and how long the hallways are as they run around in them. Then look at how small it is when they are standing outside the ship.
I even read an interview with George Lucas where he admits it's obvious that the scenes inside the Millennium Falcon don't make sense because the interior is much too large.
Sorry to burst your bubble...
