If you have transparencies which you want printed using an analogue process (not an unreasonable wish) then consider using an inter-negative and RA4, as widely done even when Ilfochrome/Cibachrome was a current process. The dedicated inter-neg materials are gone of course, but Portra should be capable. I haven't got round to trying this myself unfortunately, it is a project for 'next Winter' which of course never arrives...
