For starters, it would help to know how the Omni universes are related to the IH universes. If Omni 01 and associated universes were simply just 4 or 5 more universes in the IH omniverse, then rules involving time travel for IH would directly affect how it works in GC. Namely, there would be none.

On the other hand, perhaps Omni is separated from IH enought to have diferent laws of physics, in which case time travel can be implemented. If that is the case, then there are several options.

Firstly, there's parallel universes, which would be useful because it would throw paradoxes out the window and make for some interesting story ideas. Perhaps a character could end up crossing into another universe and meet himself? However, there is meant to be only one universe, which is more than enough room for putting stuff. There's a reason the word "Omniverse" was removed from the title.

Alternatively, instead of treating paradoxes like an elephant in the room, we could embrace them. After all, Omni 01 itself is a paradox created when I went back in time to create it. As an example, let's use the Grandfather paradox. Suppose you go back in time and kill your grandfather. Which is kind of mean, so let's just say your time machine landed on him and squished him. In your grandfather had never lived, you never would've been born, would you? But if you hadn't been born, you couldn't have killed your grandfather, so he'd be alive. Then you would have been born, and you went back in time and killed your grandfather. Thus, you were never born and your old gramps never got squished by the time machine.

The Grandfather paradox is a classic time paradox which we still haven't figured out. Perhaps it's simply impossible, and thus time travel is impossible. Or to solve the paradox, as opposed to getting erased from history, you survived, but history is reset and you're the only one who knows it. You're the only one who remembers your life, or the parent who was never born because of your grandfather's death. Is that even possible?

Maybe time travel can still exist while using the Novikov self-consistency principle, or at least an altered version of it. Essentially, history can be altered, but it will find a way to reach the same outcome it would've had you not gone back in time. Suppose you do kill your grandfather. If that's the case, your parent falls in love with a different person and you simply have a different grandfather. If you try to kill every potential grandfather you could have, a sure sign that you've probably flipped out, then you face death by Harbinger.

Anyway, that's my two cents. I'm not an expert, so feel free to criticize if you wish.
