Made some more changes. Removed another Mother-32, down to just one now. My plans have definitely changed quite a bit since my original inception, but I think in it's current state, it is highly functional, and I shouldn't be losing much by removing the second Mother. Added a Maths, because everyone and their dog has been telling me to add a Maths. It is going to take me forever to figure that one out (I watched a few videos and I'm still just as confused haha). Also added an MI Edges and the upcoming Rings. The Rings sounds fantastic, and perfectly inline with many of my other modules, and I figured by adding the Edges, I'll be getting a lot more flexibility. Besides, chiptune is fun! Replaced my Outs and Attenuator with an Intellijel Audio Interface 2, gaining a nice input for if I want to integrate samples or one of my other standalone synths into the module (I may end up just running and output from my main studio mixer into it). Switched the oscilloscope back to the Data unit, as it's much nicer. I have everything either on it's way to me now, or ordered/preordered, with the exception of the mother-32, drone commander, clouds, rings and dixie 2+ (as they are all out of stock/not released yet).

I'll totally do the same changes! Haha I think we have the same logic when comes to modular. I also had a MATHS planned, and confused,too!
If I were you, I might add more mults, just in case you want to split more CVs or clocks.
Here is mine plan, I don't have as big budget as yours :-), hope you can shine some light on it:
