imo they could have resolve the problem by just doing, like, Locutus but again. Unoriginal, sure, but there would undeniably be some interesting ground to explore with Picard encountering another of the Borg's chosen speakers, some other poor soul selected for the same role he once served. It would make the themes of his trauma in First Contact that much more personal, he could have gone on an unhinged mission to free that soul trapped in the same hell he was once in.
But sure whatever a Queen I Guess, Slaayyyy
