Is it possible to condition a craft in the vanilla crafting methods? (solved: it's not)

I want to make a (mod)recipe that gives different (mod)items depending on a certain NBT of the player.

All the tutorials I saw happen in a custom GUI of a custom block, but I want it to work with the standard crafting table and the player's "mini 2x2 crafting table".

I was thinking of doing an iteration to detect ingredients in crafting table slots. Detect the ingredient with the lowest amount and place that same amount of [result item] in the result slot. But I can't find how to get or set the crafting table slots.

Does anyone know if it's at least possible?
