I have optically printed cross procesed e-6 film normally processed in c-41 home brew, with the ferricyanide /bromide bleach under discussion.

When printing, I still project though a sandwich section of unexposed and processed c-41 film to provide the correct mask to tie to the dye sets in the ra-4 paper I am printing to.

Then you pick which colour in the print you want to be realistic ( if any) with your enlarger light source filtration and let the other hues distort as they are want to do in this process.
