You could always use 'chroot' to move the effective root directory
and read the files in to an alternate directory structure. This
saves having to edit all the file names. Of course you may need to
make a duplicate of /bin/sh, /bin/tar, and mknod the tape device in 
the new "root" directory ( alternatively a couple of well chosen 
symlinks would be even better, if you have them). Writting a program
seems to be a bit exessive.
