Comments of chapter undefined of GREED: ALL FOR WHAT?

I just thought of something here, would it be possible to break a universal rule if they did what Loki did in the series? How to look for temporal flaws and thus be able to return to the past? Soverick would be able to look for these gaps in the empty universe and they would be able to send something to the past, it doesn't have to be a legion but it could be information with the help of legion 7.
