I wonder if that is even possible??
I'm not a chemist but I do believe this should be for this reason - building the mix on my face doesn't burn the skin - which indicates that each component of the mixture is benign or non-reactive with each other and chemically stable within the same ph range.
I for one would find a 'Hydrolast Method Shaving Stick' an immeasurable benefit. It's been very difficult for me to reproduce a good mix in the near three years I've been DE shaving. A Hydrolast Stick would remove the challenge of building the basic mixture of slag, cutting balm and paste. It would also allow for customizing, adding a velocity buffer or paste to the base mixture. This would also prove to make an enjoyable shave far more accessible to the first time DE shaver. From there the market will take care of itself.
