Interesting! Some 25-30 years ago I used to make 2 bath developer with B bath consisting of 100g of Potassium carbonate, 10g of sulphite and 2g of KBr in 1L of water. B bath was used multiple times. Objective was to get maximum film speed and I was unable to buy Tetenal Emofin so I had to make my own brew. It worked but with little less film speed than Emofin.
So Juan, go for it! Even if you fail it will not be nuclear melt down, just some film burnt and some experience gained. Good luck with experiment!
