Kind of hard to say what I'd do since we don't know what the continuity is like, but I'd probably build the hook of the book off Karen taking her company interdimensional; Starrware would be the business dedicated to developing dimensional travel. Starrware would be the first company to have holdings on different realities, sharing data in scientific R&D, opening up new markets for merchandise (selling earth-4 cars on earth-1 because earth-4 has a better engine with better gas mileage, that sorta thing) and I don't know what else.
So that'd give us some cool sci-fi exploration themes to toy with, as well as some interesting business/political stories, etc.
If I could say that earth-2 wasn't destroyed in COIE like Karen thought, then earth-2 becomes her Smallville (once she discovers it's still out there); the place she goes to visit home. There we'd have Kal-L, Lois, and Karen's besties Helena Wayne and Lyta Trevor. As Starrware sets up a more permanent place on that earth we'd have to bring in some people to work for her, and there's probably a few established earth-2 names to use there as well as original characters to be introduced. But Kal, Lois, Helena, and Lyta would be the main 4 supporting characters on earth-2.
On earth-1 we'd have Atlee, and I'd use Tanya as a new intern or researcher (how old is she?) at Starrware but have her retire from heroics. I'd probably pull a few scientists from the Super-verse that everyone has forgotten about, as well as characters from her solo who had potential (I'd have to read it again, I don't remember any of them). If nobody else is using him, I'd steal Vibe and use him as one of Starrware's major assets. If not him, then Sideways would work, or any character capable of breaking dimensional barriers that Starrware could base their technology off of.
If I got my way, obviously Dick would be her love interest and be a major supporting character. And we'd have her friends and peers from the JSA and JLI show up on a semi-regular basis as well. Karen's got friends all over, and they'd all show up occasionally. Even Harley (though very rarely).
I'd likely run a fairly small regular supporting cast, and have a fairly wide circle of recurring faces; people Karen sees a lot but doesn't really interact with much, similar to the old triangle era Superman books where even Perry White's assistant had a name and appeared fairly regularly but rarely had any impact on the story.
And keeping a small cast of regular supporting characters would allow me to have fun with the doppelgangers; earth-1 Dick Grayson is her boyfriend, but she'd also run into the older Dick Grayson of earth-2. Half the fun would be seeing Karen interacting with different versions of the same person.
