Is there any hope of doing this colorimetrically?
Just a thought - if you have a spectro, can you take readings directly from carefully chosen points on the artwork itself, then sample the corresponding RGB values from your photo? (After blurring or otherwise averaging the relevant points in the photo)
It's easy enough to augment an Argyll .ti3 file with additional measurements.
