Without rules tweaks? Nope.
Either you can treat the making of magical ink like a standard by-the-book "craft" roll, in which case it takes far far far far far far too long to do, or you can ditch those rules and come up with something else.
I told you what I did, but the idea of having a Create Spell/Scroll Ink feat that allows for vastly accelerated ink manufacturing works as well. I wouldn't have an XP cost, though; I'd require the rare ingredients.
