I had the pleasure to meet and interview Mirko at the Adox works for an article a few years ago, (unpublished so far), and was very impressed by his dedication to the brand, his commitment to traditional photographic film and paper and research into producing new materials, or in the case of PWT, bringing older products back to market. There's some serious testing going on in Bad Saarow! If it can be done, he will do it, but I would think it will take time unless anyone wants to contribute some tens of thousands of Euros to speed things along.
Contrast tests seen on line look very promising so looking forward to trying out the new paper when it happens. Also, the cadmium free PWT was fine for lith printing. Recently printed some for a client on some of the last batches.
