Not a good chance of that I think; though it could have been a great addition to the mechanics.
The first Witcher game had an EXCELLENT alchemy system; which they gutted in the sequels. The original system allowed for the concoction of potions by using whatever was available that could work. Component ingredients all had alchemical properties, and the recipes called only for the properties to be present; the alchemist could mix & match ingredients as they needed, in order to obtain suitable properties for the brew.
But there was another aspect to it as well. When all of the component ingredients had a property common with the alcohol base, the brew was exceptionally potent. This was an effect that the player could cause through deliberate selection of ingredients.
All of it is gone now—simplified to base crap for the base market.
