So you want only 2 opposite of the 6 sides to have the empty space adjacent.

Not sure what you mean - expanding the box uniformly would give empty
space on 3 sides, none opposite.

Just 2 sides opposite? You could expand the box by a factor of 3 in
one dimension, then write a script to shift that dimension's coords
by a factor of one to put it in the middle. In 2D you'd have:
