I prefer the 4E cosmology to The Great Wheel. However, I prefer some of the 3E gods to their 4E counterparts. I'd like to see the 4E cosmology as the base model, but with more of the personalities from 3E fit into it.
That being said, if the default assumption of D&D Durango is The Great Wheel, I highly prefer The Great Wheel functioning like a clockwork series of gears in which the planes do not have a static place. It's a crude diagram, but I tried to illustrate what I mean below:
...2....A...
1.o.3.o.B
...4....C...
1, 2, 3, and 4 represent a set of planes which revolve around a 'gear' of the wheel (represented by 'o'.) A, B, and C are a second set of planes which also revolve around their gear. As you can see, the two sets overlap, so this creates the possibility of a plane being moved into a rotation and/or location where it normally is not located.
...2....A...
1.o.3.o.B
...4....C...
...1....A...
4.o.2.o.B
...3....C...
...1....2...
4.o.C.o.A
...3....B...
...4....2...
3.o.1.o.A
...C....B...
