DOP materials, after development, still have the rest of the undeveloped silver
in the emulsion prior to fixing. Most true toners are unselective; i.e., they
will react with both the developed silver and undeveloped silver compound. POP
"toners" usually work by depositing on the developed image only. Still, it
would be worth some experimenting to discover if your "theory" would work for
DOP. In any (insofar as known) uncharted field, experimentation is the only way
to get answers.
