That 4x4 mixer doesn't seem worth the space. There's better ways to do most of that.
Add as many active multiples as you can stand to spread those expensive-to-generate signals around, accuratly.
I like the MST '07 Buffered Multiple and the Rides in the Storm QAM.
Another boring module is the lowly offset/attenuator.
The Doepfer A-183-2 is a simple, clean one channel 4hp one.
The Frap Tools 321 is a nicer 3 channel one in 6hp
The Frap Tools 333 Sum and Distribution lets you transpose and wobble 3 channels of note CVs, and more, in tune.
These utility modules are the glue that unifies everthing you have into a systemic whole.
