Okay, so according to the leaks, Gojo is considered as the cause for Shibuya Incident and he is permanently exiled from jujutsu world. Also, breaking his seal will be considered a crime. Even principal Yaga will be executed. So, it is clear that higher ups try to find their own way by using current circumstances.

Now, Geto has prison realm, basically Gojo itself. I’m thinking about what ifs here but I think if the seal will be broken, Gojo will be soooo pissed about the events happening. And when I think about his hate for higher ups and his exilement, he won’t turn back to the jujutsu world even if he will be to. Simply put, I think, his resentment and ideals will make him away from that world, which actually brings another possibility on the condition that Geto comes back to himself. If something like that happens, I think, there is a possibility that Gojo and Geto will collaborate beacuse their ideals will have become similar until that time. We know that Gojo is not pleased about the current jujutsu world, soooo... Even if Geto won’t come back, I think Gojo may still become evil because it really is too much for him to tolerate.
