For the fixed-size case, the UUID copy feels a bit kludgy smoehow.

Just detached smalldrive.vdi and put bigdrive.vdi in it's place, and it booted right up (then the Windows drive expansion as you mentioned).Given how easy it was, I'm going to stick with fixed size disks, for whatever small performance benefit it brings.
