Allow me a little addition:

The first parameter to find should be a directory. If you are
already in the directory where the files are stored, use ".".
Note that using -iname will also process *.Txz or *.TXZ, if
that is desired.

If you want to remove the extension, you don't need to use sed
for this: The shell - I assume it is sh - can do this for you:
For example, if txz="foo-1.2.3_4,5.txz", then ${txz%.*} or
${txz%.txz} will be "foo-1.2.3_4,5".

See section "Parameter Expansion" in "man 1 sh" for details. :-)

Another suggestion would maybe be to omit the "store, repackage,
delete" step and use a pipe. Maybe it would also be possible
to omit the "extract" part altogether: Have xz only decompress
(result is a regular tar file), then bzip2 recompress, that could
also be possible without a temporary file if you can use |.
