Yup. If you have the RAW, that would be the way to do it.
But, as the prison warden in "Coolhand Luke" said, "I think what we have 
here, is a failure to communicate!"   ;-) 
Not really a failure to communicate, but possibly a misunderstanding of 
interests.

• I think Bugbear is advocating this as a nice and quick way to get the 
most from a single jpeg image. And I think he's right — it looks like a 
neat trick to faux enfuse a jpeg and get a better image.
• Other folks maybe think one should use a RAW file instead, which is also 
right, but he's talking about getting the most from a jpeg when you don't 
have a RAW file. And presently, I can't take RAW images.
• And in addition to these points, I'm curious about the theoretical and 
practical aspects of this image processing method. Unfortunately, I don't 
know enough about image processing to figure it out for myself. It seems to 
me there is some loss of detail in the highest highlights. But is this just 
a figment of my imagination? Is it endemic to improving the image and 
impossible to avoid (even with a RAW file?) Is there a way to avoid it by 
changing how the method is used? As an example, if one uses this process on 
a single, well exposed, high bit depth image extracted from a RAW file, how 
does it compare to enfusing several exposures extracted from that RAW 
file? etc.
