That's about what I was going to suggest, creating Lab values with
known delta distances from a reference Lab and simply converting that
to CMYK. To keep things simple, I was thinking delta chroma going out
from the center/reference color, delta hue going around the patch and
then delta L* for luminance.
It would be awesome if someone could come up with a calculator that
would calculate all the possibilities for a delta e of <x> away from
a reference. Humm...I may have to do some poking around and see what
can be done.

Nice script, but I think it's not at all what Rick expects.
(Constant Delta E between the patches, patches along the a, b and L
axes), maybe something like this:
