Two parts to this idea, for greater flexibility:

• Make the crafting module's pipe emit a redstone signal once it delivered all items required for a craft (since it delivers them in an arbitrary order based on which items are available first and the distance to the container) this doesn't work because comparator output is already reserved, and pure redstone output would be incompatible with the redstone module :(
• Add a mode to the crafting module that causes it to deliver items in the correct order. It should cache the delivered items in the crafting module itself and then dump them all into the adjacent container in the correct order once they all arrive. Could be called something like "blocking mode" maybe
