A round about method :)

The HF program Leveller has some neat tools for working on 16 bit
greyscale images. Unfortunately it will only accept 24 bit .tga
images as input. You can convert your 8 bit grey to 24 bit tga,
import into Leveller, apply a wide variety of various filters to
it, and then export it to 16 bit grey for your final work. A bit
of a round trip but possible.
