In my side by side, which I use for standard food storage purposes, the freezer and fridge sections are separated by an insulated panel about 1.5 inches thick. Aside from the fact that the front-facing edge of the panel provides a sealing surface for the gasket of each door, it appears to serve no other structural or functional purpose. I believe it could be cut out except for a two or three inch perimeter to leave a door mating surface, and to otherwise open up the entire unit and make it one airspace. It might look ugly on the inside, but it might also give you more space than the other fridge. Just a thought.
BTW: Were I to climb up on my soap box, I would be situated alongside olllllo.
