As others have related, I would think that it would be better to try a paper developer as a film developer rather then the other way around. I do use Dektol at varying dilutions for my negative masks. I use ortho lith film which is a different film then photographic film. By using Dektol at a 1-30 dilution I can arrive at a continuous tone negative from half tone film. At conventional paper dilutions with Dektol the result is a high contrast (black-white only sharp cutting mask). The results with a panchromatic continuous tone camera film may be interesting.
