The zimmer set of textures are indeed what I had in mind.

You could probably do something pretty good with vanilla or boom constraints with mostly stock textures. The E1 sky would give you that fitting overcast along with green hills and cliffs (pic related is from Skulltag, it's a bit taller, giving you more of that melancholic grey sky). Hexen has some trees which would be suitable for marshlands, as well as a few reasonably natural looking rock and stone textures which would fit for making big bolders and rock formations for breaking up the layout. I suppose it also has a swamp-water texture.

Further detail can be added with the occasional use of middle textures to make some treelines up on top of cliffs, as well as some bushes and some occasional tall grass.
