I was. In-universe SR-1 is 120 or so meters long. SR-2 is twice larger. Neither interior matches their exterior at all.
The actual Normandy would have to be heavily wrangled just to be sensible.
Helmsman is in the most exposed area, CIC is near the elevator, which also happens to be rather far away.
Measuring SR-2 by the cargo area and the shuttle proportions increases SR-2 to a size of a cruiser, and increases cruiser size to 1.5km.
