Note that Conway's law states that systems will be structured according to how humans communicate. Often, for dev teams, that aligns with how the APIs interact, but for, eg, testing teams, doc teams, devops, etc, that communication might be all the non-functional stuff that doesn't have to be in code per se but is still valid communication, and will still drive org structure per Conway. So I think your idea is still compatible with Conway.
