Then blend that image with one properly exposed for the foreground (possibly with some intermediate exposures as well if those two extremes differ by too many stops).

Note that the sun is massively overexposed in all the shots where the sun shows up as a star shaped flare, while the sky surrounding is more normally exposed. If you're looking for that sort of effect I think you need to have a clear sky to contrast with the sun rather than clouds which will scatter and obscure the flare (that and a lens with flat rather than rounded aperture blades). Most folks prefer rounded blades for the cleaner bokeh they produce, but if you want sharply defined diffraction highlights in your flare flat blades are the way to go.
You're probably right. A full HDR bracket of maybe 5 shots. The trouble there might be in the blending. If the cloudy/foggy area around the sun is also underexposed it will be hard to get it to match the normally exposed sky. It's just odd that to the human eye the sun behind the clouds or fog is a nice round disc and yet there seems to be no easy way to get a modern DSLR sensor to record that same image. I'm sure it's possible. I just need to keep at it. Next time I have the chance, I'll grab some bracketed shots. I also have an ND filter coming, so that may help.
