I read that Tina Louise was under the impression that Gilligan's Island was supposed to be a show about Ginger Grant!
Well, maybe that could have worked, if they revamped the other characters a bit.
One of the problems with the Courtship of Eddie's Father was, he was such a nice guy, he wouldn't stay unmarried for long.
The spring of 1972, it was canceled, and in the fall, All in the Family started its run. It dealt more directly with lots of controversial topics.

So, the pilot episode of All in the Family could have been a two-hour movie which serves as the series finale of The Courtship of Eddie's Father.
Tom gets married to Brenda Benet, Bill Bixby's real-life wife, who starred in one episode. He also gets transfered from Los Angeles to New York, to edit a new magazine from the same publisher.
One problem is how to work in All in the Family. Mike Stivic gets a job as a photographer at the new magazine, and has a lot in common with Norman Tinker, the hippie-ish photographer friend of Tom Corbett. (And speaking of which, in-jokes about Tom Corbett Space Cadet would be mandatory).
So Tom gets invited over to dinner, and meets Archie Bunker.
Now that could be enough, but there's one more ingredient we could include.
A reason a popular TV character didn't get married was that he was gay. Now, gay marriage would be completely out of the question in 1972, though gays were talked about in All in the Family. Tom Corbett wouldn't be gay, and I don't know if they could have Norman Tinker come out as gay, but it's an interesting thought.
A possible spinoff show would be All in the Courtships, about Norman Tinker and Mike Stivic, one gay and one straight. (OTL, they had Mike and Gloria get a divorce. So Mike and Norman would go to a California commune and the sitcom/dramedy would be set there.)
You'll notice the kid gets short shrift here. Oh, well. Once the dad gets married, what else is the kid going to do?
In the 1990s, they could have Wilford Brimley as an older Eddie Corbett, in a new show set in the future, called The Courtship of Eddie. He's a widowed grandfather, and his grandkids are always setting him up on dates. There are frequent references to the original series.
In 2004 there could be a half-season of animated Saturday morning episodes of The Courtship of Eddie's Great-Great-Great Grandson. Eddie's still alive in the far future, everybody's living on a space station, and he's always trying to help his great-great-great grandson and his other descendants, who tolerate him but don't really need his help with their relationships.
