Before commenting, I have a question. How does ease-of-use come into play when you're using stand-alone equipment? Some modules require a lot of diving into the manual and committing to memory all of the functionality and semi-secret button pushes and combinations to get full use out of a module. While a single module isn't too bad to learn... it's a bit of a challenge to commit an entire rack of modules to memory without spending a lot of time with them. The Mutable Instruments stuff definitely falls into this category: multiple modes that are only accessible by knowing how to get to them ahead of time. I'm not saying this is good or bad... it's just a matter of personal preference. My preference is one knob per function unless the module is really worth my time... again... my preference.
Another consideration would be the number of modulation points on a module. Take for instance your ADSRs. Zero modulation points... just a gate input and an output. I think I'd want at least one ADSR that has modulation points for the four stages. This will allow you for more expression in your system which (in my opinion) is the power of modular. Also, your EMW LFO... same story. You have 3 LFOs... cool... but they are out there in the wild and seem to only have only rate control and one waveform. That doesn't sound like a lot of fun. Something like a Xaos Devices Batumi + Poti expander will give you four LFOs with lots of CV modulation and multiple waveforms to choose from.
The last thing to touch on is outputs. A stereo output is fine. But if you're planning on recording a live set, you may want multiple line-level outputs if you plan on mixing your music after-the-fact. There are a lot of options there... again it's about preferences...
