Getting the sshlogins from stdin is easy:

    ... | parallel --tag --nonall --slf - fixThings.sh

But it seems you have found a bug: --transfer does not work with
--(n)onall. Otherwise this ought to work (THIS DOES NOT WORK NOW):

    ... | parallel --tag --nonall -S - --transfer fixThings.sh :::
file1_to_transfer file2 3rd

--basefile works, though. So maybe you can use that as a work around.

    myfunc() {
        ... | parallel --tag --nonall -S - --basefile "$1" fixThings.sh
    }
    export -f myfunc
    parallel -j1 myfunc ::: file1_to_transfer file2 3rd

It is unclear to me whether it will be easy to get --transfer to work
with --nonall. Patch welcome.
