Oracle hosts many OSS project, among a version of Yast for RHEL5 http://oss.oracle.com/projects/yast/ Would this be an interesting feature for Fedora?
It's not interesting for yum, at least.
If you think it's interesting, you can build a package and submit it for review. See https://fedoraproject.org/wiki/PackageMaintainers/Join for details. Without a willing maintainer, there's not much Fedora can do, though.
