I would do this if I had your gear to choose from.
You can put the distortions into the fuzz channel as well if you never plan on using fuzz and distortions at the same time. And the Omnicron can go literally anywhere else since Darkglass has really good blend functions. I would put the preamp either into the clean channel or in front of the whole thing before it hits any of the channels if you want the eq to affect all effects. You gotta test out what works best for you.
