I think it might get you an excellent starting point, but I wonder about staining developers and this method. I might compare Pyrocat-HD just to see. Not so much about the stain, but these developers rely on the stain to alter the final brightness range. Just curious and I'm going to try this with some D76 to see if it gets me close to what I already have for a time. If this works I'm writing it on my bathroom stall so I can read it several times a day. JohnW
