That's certainly the way I'm trying to go. I would like to see a full-feature BSP as the 'default' for the board that can easily be customized to reduce the size / boot times for 'full embedded' use. If only I could work out how to get it to work ;-)

It also needs some extra 'stuff' to pull the image together - there's a Broadcom-provided binary that has to be used as the first stage when booting, but the first step (as I see it) is to get a working kernel image based on linux-yocto 3.0/3.2.

That would be really nice.
