Hmm. Here's an interesting idea combining GC and HSV ETM. Don't ask me how I came up with the math to derive these parameters I'm going to tell you. Your head will explode.

In any GC shader (VSS or otherwise) set the gamma to 1.3. In VSS skin, drop PM:SSS to .3.

Using the D3D Render Firefly dialog, set the tone mapping gain to 1.33. Note: The gain is not labeled. It's the first number, next to the Enabled checkbox. Set the exponent to 1.4.

See screen shot.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
