Well, you could automate it.
Like, it would take anything in, but once it got one chunk of stuff, it would ignore everything that did not make a recipe with that one chunk.
Like, if you had a recipe of Plumbia and celestian, as soon as the celestian went in, it would ignore titania, unless celestian and titania was a recipe.
In some ways it was faster.
Just feed two streams of resources in, and blocks would pop out the other end at max rate.
