We need to have a way to demote both of those mats to empyreal fragments and dragonite ore respectively. You can already do this with Bloodstone Bricks to Bloodstone Dust, so there is really no reason to not have those recipes in the mystic toilet.
This is especially relevant given that the Magnanimous utilities all require 100 of dragonite/empyreal/bloodstone to make just 5 utilities and they are account bound.
