I took the dwarf heaven site, removed the history and name seeds and increased cave frequency and size enormously so that megabeasts would survive better. I set it for 5000 years, turned off erode extreme peaks, and doubled the erode cycles.
As a result, here's a spot sort of like dwarf heaven, but not quite as good.

To find the embark site, enter these settings into find:
6x6
Flux: yes
Chasm: yes
magma pipes: yes
underground river: yes
HFS: yes
There won't actually be flux, but it redirects to this site still.
Features:
Hunted mountain range
Forested areas
Two chasms
Underground river
Magma Pipe
HFS
Lots of aluminum and platinum clusters
Gold, tetrahedrite, and copper
Sadly there is pretty much no iron ore here, although the terrain is interesting and extends up a decent number of Z-levels. The magma pipe and one of the chasms starts out exposed from the surface and there's no aquifer.
I'll post screenshots when my computer is done being a jerk.
