I also have a Naked Boards MC- 8 to control parameters of the Zoia, which I mostly use as end of chain effects and some utilities.
I still have a Make Noise 0-CTRL on order from when I first set out on this costly journey.
I have not purchased the Data Bender, the Ochd, and the Quantas Ampla as money has run out. In their place I have a tides knock off, an ornament and crime knock off, and a Doepfer 6hp 8xVCA. I need the ducking possibilities of the Quantas Ampla and don't really need all 8 VCAs on the Doepfer so I think thats a good trade. I have mostly been using the O&C as a random generator or a sloth and I have been using Tides as modulation as well. The hope is to replace those two with Ochd and create room for Data Bender. It wont be as good, but It should fill the role. I feel like I could use more random once I lose those two, but space is running out.
The drum skiff is probably the weakest and will be the next thing to overhaul when time/money permits.
