What is a .tmp file in this context?

jigdo can create the complete iso, though.

Did you see the thread on fedora-test-list?  I did exactly what you
suggest, but using jigdo to create the iso.  You could then start bt
on the iso to provide a seed.

Yes.

It should work.  There should be no reason that bittorrent would need
to fix a bad download, because the .iso created by jigdo should be
complete and md5/sha1 correct.
