Looking to build a list of unobtainable and unplaceable items

Hello I am currently working on a data pack for item trims. The server i run is looking to add many trims as reward items. And So the blocks im using to replace in need to be unobtainable, and unplaceable in survival. And currently i have everything working, the entire datapack works. But i haven't figured out way to get crafting recipes to use anything other than the base item as crafting material so ive been limited to 5 blocks Structure Jigsaw Command block Command block chain Command block repeating All 5 of these seem completely unusable in survival mode and can be used in custom recipes without any issues. But i cant find anymore like these in the game to replace. and i want to be able to add additional trims templates to my pack. But i cant find anymore blocks to swap. So my question is. Does anyone know of more blocks i can use. Or does anyone know how to set additional data in a crafting recipe to make a single block work based on some other data on the block
