I want to try my best at giving LIFE WITH LUCY a premise that would've worked better than the one we got. I'd probably re-title the show TOGETHER AGAIN and make the show more of a romantic comedy rather than a straight sitcom trying to duplicate Ball's earlier successes. The key to my revision would be the chemistry between Lucille Ball and Gale Gordon, but dramatically changing their well-worn on-screen partnership into a romantic relationship instead of a boss-employee dynamic.
Here's what I'd do (and please pardon the randomness of this):
Lucille Cooper (a name paying homage to her MY FAVORITE HUSBAND character, Liz Cooper) marries her high school sweetheart, Curtis Barker (keeping the tradition of an "ar" surname), in a small, simple ceremony at a courthouse. This would be the opening scene of the new show. Two aging, high school sweethearts have rekindled their old feelings, both preparing to live out the remainder of their golden years in wedded bliss, following the passing of each of their spouses.
Lucille and Gale honeymoon, and then come back home to South Pasadena, California. Once back home, the two are lured into buying a small hardware store from local businessman Hugh Wallis (maybe cast some old-time comedian, like, say, Steve Allen for an episode or two). The two decide to sell their old homes, lease a small apartment, and run the hardware store together as they enjoy their semi-retirement.
This keeps Lucille and Curtis in the hardware, a primary setting for LIFE WITH LUCY that I like, and think could work if used properly. This would also keep hardware store worker, Leonard (still Donovan Scott, who I liked on the show), in the mix, most likely as a regular cast member.
In this make-believe version, however, Lucille would be a little wiser, and Curtis would be a little less grouchy. They're newlyweds after all, so there's got to be some lovey-dovey stuff going on in some capacity. They could have newlywed squabbles, sure, like learning to live together and sharing their space, but the outright hollering would be eliminated. Lucille could still be a bit of goofball, and Curtis could still drop his slow-burn one-liners. But let's modernize it some for the 1980s. Let this reworked show balance the middle ground between the family-friendly and the more adult-aimed sitcoms of the period. Maybe lean more into the maturity of the characters, as in their ages, but keep it on the cleaner side in terms of language and subject matter as to not alienate Ball's long-time fan-base.
Of course, Lucille and Curtis have children from their previous marriages. Curtis's son, Ted (still Larry Anderson because I thought he could've been good with the right material), works as an architect. He is already settled in South Pasadena as well, and he is supportive of his father's decision to remarry. Then there is Margo (I wouldn't keep Ann Dusenberry, but I haven't any idea who I'd re-cast this part with), who is Lucille's daughter. She decides to relocate to South Pasadena from San Francisco to keep an eye on her mother. Margo is worried that Lucille is making irrational decisions with her finances and lifestyle choices. In this incarnation, I would not have Ted and Margo be a couple. They would know one another, naturally, but further story could be drawn from their separate careers and romances. I'm also divided if I'd have Ted and Margo as regular cast members. With my reworking, they would probably work better as more recurring characters. I might let Ted be seen more as he is already rooted in South Pasadena but might rewrite it where Margo stays elsewhere in California and therefore isn't seen as often.
There would still be physical comedy in the show because it's Ball's forte, but I'd make that minimal. I'd push the focus more on the relationship between Lucille and Curtis as newlyweds and play with the romantic comedy angle instead.
Back at the apartment building where Lucille and Curtis live, they would have a neighbor named Audrey Manners (Audrey Meadows in a regular role). Audrey could be an old friend of Lucille's, and therefore she'd be quite familiar with Lucille and Curtis being high school sweethearts. Other side characters could be played by mainstays of Ball's long TV career, like Mary Jane Croft, Doris Singleton, Vanda Barra, and Carole Cook. I would really like to find a way to use Carol Burnett and Shirley Mitchell in the mix somewhere, too. Burnett, being a fan of Ball, just had to make an appearance, if only for an episode or two, and Mitchell could be a frenemy of Lucille's or maybe Curtis's sister-in-law from his first marriage. There could also be opportunities to possibly other old-time comedians, like Jack Benny, Jack Paar, Bob Hope, and I'm sure Ball could recruit some other old-time stars to appear in guest roles—but not as themselves, but as actual characters.
This reworking of the show would cause multiple drastic script rewrites to the thirteen episodes we got of LIFE WITH LUCY. If I get bored enough one day, or if I get the hankering to, I might just write-up some plots for potential episodes
of TOGETHER AGAIN.
