Thanks, I'm glad you like it!
There is a mod option that disables needing Crucible intermediates for Aquilo recipes.
It's not really viable to get quality hydrogen filament from quality denatured hydrogen, for the reasons you mentioned, and because a bunch of the recipes don't accept quality modules (though this may change once Factorio 2.1 is released because there will be some more flexibility in the modding API, but I digress). Instead you can recycle quantum processors directly, or you can recycle laser lenses (which will also get you quality rubies).
Also, because higher quality pressure forges have more module slots, choosing recipes that can be made in pressure forges can be helpful. A legendary pressure forge has 10 module slots, so with legendary Q3s it gets +62.5% quality (in addition to the base +50% productivity).
