The goods area will be adapted with a turntable and possibly shrunk a little for some extra scenery.
If the turntable is a must then the return loop can go, giving lots options for the green sidings.
If the green half loop is shrunk back a couple of inches. (the whole point cluster slides, at the top) then there is room to add scenery in the form of a raised town-scape over the two outer lines, with a retaining wall between them and the inner loop. The inner loop can be broken up by having a ramped access road from the goods area to the raised level, which the inner loop will pierce, next to the retaining wall.
As here, on an enlarged version (where I was trying for maximum carriage or DMU storage.)
