How to modify a hex string to LE-format before passing it to `xxd -r` to view its binary contents?

The hex string 0068732f6e69622f represents the ASCII string /bin/sh, when it's stored in memory in LE-format. Is there any Linux utiltity that will take the hex string and reverse it bytes (2f62696e2f736800), such that xxd -r -ps will display /bin/sh? $ echo -n 0068732f6e69622f | xxd -r -ps hs/nib/ I've looked into xxd -e, but it's not possible to use it with -r: -e little-endian dump (incompatible with -ps,-i,-r).
