And kernels, and random software the drivers require, and special snowflake bootloaders, ... I'd love to see it, but considering how long it took desktop Linux distibutions to run semi-reliably on most PCs which have far fewer hardware differences and important components without even partially reverse engineered specifications, I'm very suspicious this is a feasible way forward.
