Special ingredients. In theory, I like this one a lot. However, how would you implement on a mass scale that could work by the book and not per campaign. People moan and groan about every spell having a material component, but that's exactly what your adding in here, a special ingredient for every magic item. That's a lot of special ingredients.
The way that I was thinking to systematise it:
Magic items currently cost XP. Killing or otherwise overcoming monsters gains you XP.
So take the XP cost and translate that, for a caster of the minimum level to make the item, to a CR of monster that that character would have to defeat to gain that much XP, or equivalently an average CR of encounters in terrain that he must cross. The DM then chooses the challenges within the CR guideline and announces the ingredient required, to his taste and campaign specificities.
Since fighting the monsters is not part of a heroic quest, perhaps the mage gains no XP for them. This comes to much the same thing as the current system, but with more adventuring and less arbitrary crossing-off of character resources.
I expect you would want to pre-calculate this into a series of tables at existing logical breaks for each type of item, such as per spell level of scrolls or per + of magic weapons.
Example: To scribe a scroll of a 3rd-level spell, a 5th level character must obtain 15xp. If a standard party of four 5th-level characters defeated a CR 1 creature they would each gain 5 times the required XP to scribe the scroll. (Why are people complaining about XP costs, again?) Thus, the ingredients for a 3rd-level scroll should require defeat of a CR 1 creature of the DM's choice, which will provide enough materials to scribe 5 such scrolls. I suggest CR 1 as a minimum since less powerful creatures are just not impressive enough to be useful sources of magical energies.
To scribe a scroll of a 9th-level spell, a 17th level character must obtain 153xp. A standard party of four 17th level characters will each gain enough XP to cover this if they defeat a CR 11 creature.
