My own personal tastes would be wanting a little more in on-board sequencing so that I can stay-in-the-case as much as possible. I find sequencing via the computer to really pull me out of my hardware zone.
I like Maths. But for the size of this case... it's just too big. You already have the Pip Slope for an AD envelope and the Joranalogue for mixing/VCAs.
I would ditch the Maths and replace it with a Mimetic Digitalis (10HP) and an micro Ornaments & Crime (8HP) and then find a 2HP module of your choosing... maybe a reverb or delay so the Disting isn't always on effects duty.
