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 CMM
For 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,

The software is not fit for any particular purpose, and thus:

Having said that, the cmm should be able to convert from a normal matrix-based profile or Lab to another normal matrix-based profile.
Copy the decompressed file to
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.
As RelCol, but partly emulates brightness of the source image in destination space.
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.
