Where the (un)compress prog could perhaps be looked up in the existing
dired-compress-file-suffixes. AFAIK, all such commands use "-c" for
compatibility with each other, so that probably doesn't need to be an
option. So the only new config entry needed would be the tar command.
Wrt creating the archive, either make the compression scheme a custom
option, or a separate step (which would probably require "make a
tarfile" to be a separate command).
