Well, how open are you to buying new modules? For many of the Mutable Instruments modules, smaller clones exist. The resale value of your MI modules should be above the new price of the clones.

Perhaps getting rid of the Veils and Quad VCA and going with a Befaco Hex Mix? That's two less VCAs but a space savings.

Do you need the Noise Engineering BIA? Think hard on that.

The Magneto is nice. But could you get away with a Jelly Wobbler?

If you had to pick one of your multi-effects to lose, which one would you remove?
