Interpositive? Umm... I don't think bleaching is generally involved in
that process.

Do you mean reversal processing? If so, that wouldn't work. You'd
need dichromate, permanganate or similar bleach for that. Someone here
(maybe Liam?) suggested sodium sulfide redevelopment followed by
ferricyanide and fix as a way to avoid environmentally harmful bleaches
though the image may not be neutral black.
