This is pretty much what teamcraft does.
You can create lists and can add any item in there, it will give you the source an item is obtained from if it's not craftable (e.g. for Verdant Partition it shows Irregular tomestones, Saint Mocianne's Arboretum and Fête Present) or a list of raw materials including shards/ crystals if it's craftable as well a source for each raw material or precraft if they're available for purchase from merchants.

You need a profile to make lists or add your character from the lodestone so it can check if you have the Folklore/ Master Recipe tome and crafter level if necessary, so that's the only downside if people don't want to have an account on that site.
But other than that it's really neat for organizing your housing crafting session.

Cheers for wanting to share your idea with everyone else though, not everyone has heard of teamcraft yet after all and some simply don't want to make accounts for something like this on 3rd party site.
