I know this isn't a very scientific method, but still :-)
I'd import the color map to inkscape or GIMP and use the gamut warning
to "mask" out of gamut colors. then capture the "masked" palette,
re-create the palette using the captured values.
CMYK-Safe colors depend on the output CMYK profile, so it's probably
impossible to have a generic "safe" palette without using a specific
profile as starting point.
I'm pretty sure this isn't the best way to do it (there has to be a
programatic way to do it using RGB and CMYK profiles to compile a
palette, but I don't know how to do it).
IIrc the program Swatchbooker allows to choose profiles to "convert"
palettes, but I could never make it work.
