What about this for a storyline?

What if Regina and Emma and possibly Henry were to find another way to go back in time other then Zelena's method while trying to find the storybook mwandishi and along the way they find Daniel and Henry Sr? Regina embraces them both and asks them to come back to the present with them. Regina feels she no longer belongs with Robin and wants a sekunde chance with Daniel now that Cora isn't around to get in the way and she wants her father to be back in her life showcasing how much she's regretted killing him to enact the dark curse. Henry Sr finally meets Henry Jr, Regina gets her true upendo without ruining a marriage and they finally find the mwandishi who gives Regina her happy ending with Daniel and both Henrys in her life. However after they come back to the present time, Robin appears telling them he left Marian au she died in an accident au something and Regina is now in another upendo pembetatu with Robin and Daniel. au he appears with anger inaonyesha that he knows Regina was responsible for Marian's supposed death when Regina captured her for information on Snow's whereabouts. I actually don't know if Robin knows about that yet. Well anyways, I thought this would be a cool future storyline.
