I've been reading the excellent
The Time Traveler's Wife by ML Thompson and recognize the premise.
Not sure it completely fits your criteria because "Tempus Anyone?" is part of the longer story and every detail isn't retold. The episode redo is told in flashbacks/memory and is towards the end. Some important details/situations have already changed by the time canon Lois shows up.
You picked one of my favorites.
Again, it's another story, where Clark's actions in the past change what happens in the future. I don't recall Tempus's revelation about CK=SM being changed though. I thought Clark was still out as Superman at the end. (Won't say anymore if I haven't spoiled it already.)
What I really want is to have something change WHILE canon Lois is in Alt-Dimension, which makes it so she can leave without his secret identity being known.
