Have you looked at GMG’s ColorServer?
It has a Paper White Tool that allows you to measure the paper (or manually enter) Lab values and then it will recalculate the conversion profiles to compensate for OBAs.
Only takes a couple of minutes to build and, with a sensible naming convention — ProfileName+LabValues — I don’t think it’d get that messy workflow-wise.
The heavy OBA stocks seem to cluster around L92.5-93.5 & b -13 – -15 so you can probably get away with small number of adapted profiles.
Harder for stocks around b -10 and lower as you’ll probably have to deal with L values ranging from 91 to 96
Cheers
