I really like the suggestion in this thread that La Forge still could’ve become chief engineer while Worf stepped in as the permanent helmsman. That’s not something I would’ve thought of myself. The downside is that Worf probably wouldn’t have gotten much character growth in that role.
I'm not sure that's true. I get the sense the writers were quite eager to explore Klingons, even putting Worf at the center of
Heart of Glory in S1. They were the one legacy alien species from TOS that hadn't been deliberately shunned, because its latest incarnation was now associated with the film franchise. It was that movie momentum they were trying to build on, & in some ways, distance themselves from what was seen as the hokey 60s show aesthetic. Its the main reason Worf was put in there at all. It was recognizably Modern Star Trek
I think it was inevitable that Worf would get development, wherever he landed, due to the alienness appeal. It was mandated that Wesley would (due to Roddenberry) & it was inescapable that fan favorites Data & Picard would. TBH, Crosby was probably right about her character, potentially falling off in presence, after she'd turned out to be the least interesting of everybody there in season one imho, except maybe Beverly. (who was also dropped) I think Sirtis (who reportedly was also on the chopping block) only survived by being gorgeous, exotic, & doing weirdly alien things. (Plus Majel was playing her mom)
I really can't see the writing team wanting Worf in engineering. Geordi was virtually a walking advertisement for techno-plot, wearing that visor around. He, more than anyone but Data, represented the science aesthetic of the cast. Worf was a shoe-in for some kind of bridge duty IMHO. It showcased the progressiveness of modern Starfleet, a Klingon now being there.
They really overcrowded that main cast, up front. Riker mostly got placed as a young leading man type, to Picard's elder statesman, archetype, a holdover from Phase II's Decker/ Kirk planned dynamic. There was way more overlap there than I think they figured on, because Stewart surprisingly turned out to have unexpected sex appeal with the audience.
I really think Tasha was the obvious poor fit. It wouldn't be until Ro Laren, until they'd figure out the right way to write the strong woman archetype. Tasha, in that dynamic, always fell flat, played campy, or looked phony. I think she could see the writing on the wall. Most of the other ensemble players were way more interesting. Heck, even
Yesterday's Enterprise, as interesting a plot as it was, couldn't find much for her, throughout its run-time, except a lame romance, & figuring out her fate from Guinan, factors which IMHO held even that episode back some.
If she's stayed, she'd have likely been the one who went underdeveloped, & maybe Worf would've moved up to helm & Wes would've gotten his tutelage from Geordi in engineering, with input from Riker, or at the bridge work stations, upstage. He could've easily did science things back there, in his silly jumper lol
