Not a bad start. A few things jump out:
* VCAs - it seems to be a universal truth that you always need at least one more VCA than you currently have available. You'll need more, particularly if you want to start adding motion to your signals at mutiple parts of the signal path. Additionally, your fx modules and final mixer are stereo, how cool if you had enpugh VCAs for stereo signal management?
* LFOs - batumi is a wonder in a small package, and I hear that version 2 is even better. Zadar though can also do some pretty complex waveforms, but I think I would want to go with a dedicated LFO personally. In addition to batumi, consider the ochd and it's expander from Divkid/Instruo. Small footprint, but quite organic feeling motion and the expander packs some cool funtions.
* Attenuators - You'll want to tame the lfos and any other cv, particularly if you enjoy random voltages. VCAs can also work for this, if you had them to spare.

Other things to consider if you find you have the space:
* Matrix mixer (Doepfer a-138m is what I'm familiar with but there are several out there) - great for blending signals (both uni- and bipolar) and super useful for feedback. The only downside is the hp, but there are other matrix mixers out there with smaller footprints.
* Sample and hold - I just love these circuits and find them so useful. That's all.
* Comparator - Same. Specifically the Joranalogue Compare 2.
* Crossfader - WMD axys (stereo) or even the Joranalogue Morph 4 (mono). Might be useful for drones.

Hope this is useful. Best of luck!
