There is just one little problem with this
The Guide does not say the Shadow World is the Border Ethreal it says it
replaces it in regards to Aberynis.
In other words you need to go through it to get to and from the Inner Planes.
Otherwise your idea seems cool.
Also to add to this I reccomend getting the PS MC III as it has many inner-
planar monsters that could be used as truly horrifying beasts.
