This sounds like something that would be nice to have as a
post-processing step in the SIOX Foreground Selection tool. Have you had
a look at the refinement brush that the SIOX guys have suggested? Sounds
similar to your approach and still awaits implementation in GIMP. So far
we don't have anyone working on it, even though most of the code is
already in place.
