I guess you could try overlaying the old and new filesystems by virtualizing
the inodes, superblocks, directories, and other stuff in RAM, but you still
have to write it to disk, and some of the metadata from one fs will collide
with the other one. The superblock for ext2fs needs to written to several
fixed places on the filesystem, which might also be needed by
reiserfs/xfs/whatever.
