This don't work when you change a part of your equipment. Or because the value
returned by the scanner can be depending of the lamp use.
This can't work with slides scanner too!

Could I suggest another possibility (may be)?
If someone known the value of the Kodak color and B&W chart (they are not
expensive) may be it is possible to have a printout of it and some variant.
we look the variant which is closer to the reference chart and obtain the
value of correction to be applyied.
May be the the it8 reflect chart (You can find one on the web, I'll put
http://www.regix.com/regisr/files/it8ref.jpeg if you want to see it) can help
the process of calibration.
