I am intrigued by this idea.  I have been using hf_gray_16 in the past, and it
usually creates enough levels, but an hf_gray_24 might be pretty cool too.

From the documentation:
"When  hf_gray_16 is on, the output file will be in the form of a heightfield,
with the height at any point being dependent on the brightness of the pixel.
The brightness of a pixel is calculated in the same way that color images are
converted to grayscale images: height = 0.3 * red + 0.59 * green + 0.11 *
blue."

It'll take a bit of testing, but if it is that easy...
