The usual way of the "digitally pushed" ISOs is to multiply the output of the ADC to get the desired ISO and write the result in the RAW-file.

Which is either cosmetic or even counterproductive (if the RAW is bit-limited). If you multiply the ADC output digitally and write that to the RAW file, you gain nothing. If the RAW file is limited to 12 bit, you may even lose dynamic range that the sensor/ADC has otherwise captured perfectly. If the RAW file is not limited to 12 bit, the effect is null, as the RAW converter afterwards will deal with the data as it wants.
