Pretty much already had all of this working here: https://github.com/openshift/openshift-ansible/pull/10898
For single host cluster, I think path of least resistance would be to modify the bootstrap host to not pivot, make it clear it's 'not for production' and we can take lots of shortcuts for someone just looking for an easy, 1-VM openshift api. I'm most interested in running OKD 4.x on Fedora rather than CoreOS. I might try to do something with that this weekend as POC.
