Is there a chance that you could make the ‘Color Clipping’ algorithm available as a Script or Action. I’d be happy to give it a try on a broader basis.
Well, I have been busy transitioning to XCode & intel. I am still in the middle of it. Even so, here is a link to the Mac OS X CMM that is supposed to do this:
Color Clipping CMMFor those of you willing to give it a try, by downloading the file via the link you agree that:
I remain the sole owner of the copyrights,

Having said that, the cmm should be able to convert from a normal matrix-based profile or Lab to another normal matrix-based profile.
Installation:
Copy the decompressed file to
/Library/ColorSync/CMMs/
Restart Photoshop and open an RGB image.
Select Convert to Profile
Select "Excalibur" from the engine menu.
Switch intent to see the following conversions:
Relative Colorimetric intent:
As normal relcol but preserves hues in the destination space.
Perceptual intent:
As RelCol, but partly emulates brightness of the source image in destination space.
Saturation intent:
Converts source space primaries to destination space while preserving hue, then uses these primaries for the source space. This fits the source space in destination space and allows for a more accurate "desaturate monitor colors" option.
clicking the "preview" checkbox will switch between normal Photoshop preview and the selected CMM conversion. Also note that Photoshop uses a table based emulation for the preview, so there may be artifacts in preview mode which aren't part of the image after calculation.
