I like when the focus is on Superman and Clark Kent, when they are the same person. Then the extended cast is whomever he is dating, his friends and co-workers from the Daily Planet, etc.. I don't like all these child and teenage superheroes and would prefer that if they have to be around, they be put in their own titles where I don't have to read about them just to get my Superman fix.
So, I'd say I only like a "family" focus if they mean Daily Planet characters like Jimmy Olson, Perry White, Kat Grant (I realize she jsn't currently working there), Lois Lane, etc.. In select situations, you go to people like Lana Lang (non-superhero edition, or the superhero but hanging out in her human guise), Maggir Sawyer, that African-American firefighter friend of New52 Superman, Dr. Veritas, Batman, Wonder Woman, etc.. I feel like Jim Olson is barely in the comics anymore.
I could see expanding it to like having the Planet staff or the Justice League hang out at a bar after work and the bartender becoming a character, plus a Norm-like bar patron (Don't have these people turn out to be bad guys, please). I liked the scene right before Truth where Clark has lost his powers for a day due to superflaring and was out drinking with his JL friends in their human guises- that could be a regular thing they do- minus the drunken powerless Clark (Although that was hilarious). Could work for the Planet staff, too, depending on where you want the focus to be.
Acfually, what if Clark Kent, Bruce Wayne, and Jim Olson all start drinking together, and Jim knws Clark is Superman, but not thst Bruce is Batman, so Clark has to cover up for Bruce? That could be fun.
But again, the superhero kids and teens are too much already for mainline Superman titles.
Superwoman has been good as a separate book. Were that to fold due to poor sales, I could see slotting her in a Justice League type teamup book (She and Steel could be the first two members- maybe new52 Superman as well, he says sneakily
), but not Action or Superman.
And, of course, they could always give new52 Superman his own book! I know, I know... My favorite character, though.
