synthesizing yum transactions?

I have a topic I brought up in a different forum:

  http://www.spinics.net/lists/centos/msg156915.html

The core question I was trying to ask there is:

Given:

- A server initially provisioned with yum (via Anaconda)

- Subsequently had RPMs added/updated using the rpm utility directly

is there a way to synthesize another yum transaction, describing
the new RPMs, such that a 'yum rollback history 1' will actually
do what one would expect?

That URL above described the tactics I was exploring, and I feel
like I'm close, but it's not quite behaving.
