Seeing information on both lists?

Although you've already responded positively to a reply, I'm going to go ahead and offer a different view. Two views, actually. Bear in mind that I am hardly a tech consultant; but I use SPO extensively, too, and so have a "prosumer" knowledge of what it can do.

If you want to do what you asked about, which I don't really recommend, then the answer is yes, you can easily have a lookup in the "submissions" list to pick an entry from the "stories" list, assuming that they are in the same site. But, as slick as that might be, it might also be more complicated than necessary, and at the cost of some functionality.

If, instead, you expand your "stories" list to include columns for submissions (dates, contacts, status, whatever), you could not only keep it all in one place, but also search and filter in ways that you couldn't do if the lists were separate. Additionally, you could more easily use the list from your phone, because the mobile SharePoint app has no functionality as of this writing (under iOS) to use a lookup.

If you want to use the lookup feature, you could have a lookup from the now-expanded "stories" list to, say, publishers. Then you could separately keep a list of promising places where you'd like to submit or have submitted.
