update-initramfs should be able to build you the right thing.  But the system has to be close enough 
to right for it to figure out what to do.  So if you can get through some manual steps to eventually 
get the system running with the correct volumes in the correct places then it should work. 
(Obviously it doesn't have to have the same kernel if you use the right options as you'll boot since 
it doesn't do that on upgrades.)

Up to you to decide whether it's easier to get the system running by hand or to learn the initramfs 
magic to build that by hand.
