Heavily modify the initrd to do all the above steps.

The [new] code for this would be in your newly mounted system.

I don't see bootcd being useful for this at all :(

All the smarts would be in the initrd for your requirements, then the
whole system will live in RAM (tmpfs) bypassing much of the bootcd
cleverness.

After fully loading a system with bootcd I think it would be a *very*
difficult task to move everything into RAM. (Nothing is impossible!)
