I like the approach, and vastly prefer decent bootloaders with CLI's and
greater flexibility but the grub implementation falls way way short.
It's not near the same level as the FreeBSD boot loader for example,
which is doing the same job with no firmware.

I tried this very thing before, and when sdb is the boot disk and sda
entirely blank, grub seemed to still want to pull things from sda :/

Compare that to raid-extra-boot="/dev/sda,/dev/sdb" ;)

Hmm, that would be better.
