A little something I wrote last year -- A script that lets you select a color swatch to convert to the equivalent gray value, as a tint of [Black].
Used it for about a year, has occasionally been useful to me.
Download the script from http://www.jongware.com/binaries/swatchtogray.zip -- copy into your scripts folder, double-click to run. Select a swatch and hit OK, and it does a valiant attempt to change the swatch to gray.
