Lightroom and ACR: Heal Mode for Highlight Recovery

It would be great if "Highlight Recovery" had a heal mode which would attempt to use the context of blown areas to recolour them.

Highlight Recovery seems to be useful in two scenarios:

1. Highlight detail is present but current exposure, tone curve, etc. settings make them appear washed out.

2. At least one colour channel is clipped.

For case 1., it should be sufficient to apply a tonal mapping at the highlight end, perhaps combined with a mask that prevents the effect from spilling over to mid-tone areas. I guess this is how HR currently works. Ideally, it should be the inverse of "Fill Light" (i.e., use a mask) but unfortunately, the results don't look like that.

For case 2., HR should not just pick a neutral grey, but attempt to use colour information from the context to recolour areas for which accurate colour information is lost.

For instance, consider a blown area on skin, due to a specular highlight. Replacing the area with a less bright, but grey area is not a real improvement. It would be great if an optional heal mode would attempt to recreate the skin colour in the blown area.

I could imagine it to work globally, but maybe the HR tool in heal mode needs to be a brush?

I currently only very rarely use the HR slider because it doesn't create satisfactory results when colour channels are clipped and leads to overall flat looking images when they are not clipped. Reducing exposure and tweaking the tone curve often leads to far better results. This is a shame because just using the slider would be a lot quicker.
