Place the transformer in the workbench and depending on the type of transformer. With a reverse transformer, combine it with one item that you want to degrade in rarity. With a positive transform, overlay it with three copies of one resource (you can learn all recipes from JEI)
In terms of modding? If yes, I can advise you to do what you yourself would like to see in minecraft. In any case, experiment, come up with something more interesting than just new ore with new equipment that is a little better than diamond, there are a lot of such mods. Or another dinosaur mod, better come up with your own based on existing ones, then it will be more interesting. And don’t overdo it with the elements and the amount of everything in fashion, sometimes a simple small mod on a specific topic is much more interesting.
