Look at the :post header arg
(info "(org) post")
You write a src block that extracts the remote file name from *this*,
creates a local file name from it, copies the remote file to the local
host, then substitutes the local file name in *this* and uses it as the
return value.
Use the name of that src block as the argument to :post
