NO!As far as I understand, SS is only used as a preservative
Thee role of sulfite in a developer is a very complex one.
While the sulfite content of a developer can be reduced it cannot be eliminated entirely. There are several reasons for this. Metol is a hydrochloride salt and is acidic. Enough base must be added to a developer to neutralize any acid from the metol. In many formulas the sulfite acts as the only base to raise the pH so that the metol can develop. Secondly without any sulfite a developer will likely produce stains on the negatives. I would suggest looking at the Crawley FX-1 formula for an idea of a minimalist sulfite developer. Thirdly, some sulfite must be present or film speed will suffer. Sulfite acts as a silver halide solvent and thus exposes active sites to the developing agent. There are more reasons which will not be discussed here.
