It appears to me that the developer and fixer issues are not too complicated but there are at least 10 threads about home brew bleach and none of them brag about having any success making good prints. I've been processing Ilfochrome in my home dark room for at least 19 years and the process is so simple and reproducible with the Ilford chemicals it seems the whole concept is lost if you have to make a bleach solution out of hard to purchase chemicals and then find out it doesn't work.
