You can use any blocks in the filesystem, assuming you can set up a file as
you want it.  For example, if you allocate inodes until you get one in a
block group of your choice, then create a large enough file there and rename
it to "/.journal" in the root of that filesystem, umount, delete the old
journal, and then run e2fsck on the filesystem.
