Exactly. For most cases where the highlights have been lost or over 
compressed in the JPEG, all that's necessary is to extract an image from 
the RAW file with alterations to the As-Shot settings. Only in a few 
extreme cases have I found this technique to be necessary.

In PS, there is always one more way to skin a cat than one already know 
about. My method is to select whichever part is most even using the 
Magic Wand, Select by Color and/or the Lasso in one or another of its 
forms. Which tool works best depends on the image. Select by Color can 
be amazing for selecting things like sky or water seen through trees, 
etc. I then make the selection or its inverse into a new layer and drag 
it over onto the other RAW extract. In this case, it was the stamen, but 
could just as easily been the petals. Sometimes feathering the selection 
before creating a new layer from it works best, sometimes not. I don't 
know how to say except that common sense about the nature of the 
selection and experience help.

As AG outlined in his process with the lone tree image on his site, one 
may also adjust each image for the area to be used from it, put it as a 
new layer on the other, then selectively erase the top layer where the 
characteristics of the bottom one are desired. With adjustments to the 
size and hardness of the Eraser, this can become very like 
burning/dodging and feel very natural to an experienced darkroom worker.

I'm sure there are other ways I don't know about yet.
