Add per player per item randomized recipes sort of like a game had called Life is Feudal and also a crafting grid possibly 5x5 or 6x6 that allows crafting without research by putting the right combination of items and stack sizes. This would work in tandom with current crafting and research maybe a new workbench. Theres already a mod that replaces the crafting ui client and server side but I don't know how to edit it to make this work.
