Looking at your desire to make things smaller one issue is access for test. I have seen designs where traces extend through cut-able bridges to connectors, pins, what ever needed for test. After it tests out you break that portion away. NO huge .1 center headers remain !
I'll try to find an example if your interested.
I'm a retired mechanical engineer who dabbles in everything. I can help with 3D printed case designs. Here's a project I designed a case for: AVNA1. Also built the project. It works great but would probably work better with your ADC/DAC ?
