the only way to archive the wal_files from a slave into another

Yes. Though I have never tried this myself but going by the theory, it
should work.
a slave doesn't generate wal_files at all.
if your master is keeping a wal_archive, slaves, including cascaded
streaming slaves, can all use that same archive as their wal source,
these are only used for catchup when streaming is interrupted.
