The whole concern about separate payloads goes away for v3 - since
technically, the whole thing is separate payloads. But for V2, I don't
think there is a problem with building the blob and inserting it into
the final coreboot build.
For its part, SeaBIOS could have a --build-minimal-coreboot mode
(or whatever), so it would all be easy to build and integrate with a
minimum of effort. I can think of a few logistical concerns:
buildrom probably would need a seabios-coreboot target as well as
seabios-as-payload target, and we would need to figure out how to
configure both buildrom and coreboot to not build or use the minimal
seabios if seabios is a payload.
Not insurmountable issues, but stuff to think about.
