Well after writing that Photoshop didn't have a Lab oriented gray space,
I figured why not??

So this is an close approximation:

http://www.harrington.com/LabGrayscale.zip

Just download it and extract.

Then in PS Color Settings for Gray -- Load Gray and load this profile.
Its called Lab Grayscale.icm

Assign this Profile to your 21step or image.
Its not quite perfect, the 95 step is only Lab 4 but all the other steps are right.
If this is useful I can probably make a perfect one later.
