    According to Dr. Tim, each paper/toner combination will give a different result depending on which halide is used in the bleach. ie. MGFB in polysulfide will look different when bleached with potassium ferricyanide and potassium bromide than with bleach with pot ferri and sodium chloride.
    Here's the question:
    Will Posassium fluoride also give another result.

    Assuming that it re-halogenates the silver image in the same way, I think you'll be disappointed in the results: according to my Merck Index, AgF is fairly soluble in water, meaning that the ferricyanide/KF bleach step will totally dissolve away your image.
