Basically, the idea here is to identify a retcon in Superman's history and identify how YOU think it could have been made better.
For me, I'd have kept the Kents dead after Crisis.
BUT I'd have simply introduced an Aunt Sarah and Uncle Eb (Jonathan's sister and brother-in-law?) who are in on Clark's secret and running the old Kent Farm.
You get the family/Smallville connection and a change of scenery whenever Clark needs folksy advice without undoing the Kents' death. It's a lot less invasive and more of a Leslie Thompkins type character addition. It also allows for richer flashback stories.
Bonus: Sarah and Eben were alternate names given for the Kents in the 40s.
