With regard to a lot of other TOS species (and some TNG ones too), here were many that seemed... silly? Giant glowing spheres with aliens that were essentially children? I'd rather have credible aliens in a new show; ones that we can believe in (within the realm of Trek and Fiction). I know Trek is fictional anyway, and hypothetically anything is possible, but I'd still prefer more credible results. I don't think a new show is going to be taken seriously if the aliens we meet are like half the ones on TOS and early-TNG.”
If they did re-visit any original series aliens presumably they'd update their appearance as they did with the Klingons and Romulans and as Enterprise did with the Gorn. I actually think it might be interesting to follow up what happened to the Federation's relationship with the First Federation. How did the Capellan's fare after Kirk's visit? Could we see more Suliban, Denobulans, Orions, Andorians and Deltans? Xindi? What about the development of Tyree's people? If there's one doomsday machine, there's likely another one built by the first one's opponents. What happened on Sherman's planet? Did anyone ever go back to the Guardian of Forever? And what about that energy barrier at the edge of galaxy?
The list is almost endless, and many have been revisited already since the show aired in books and/or comics, but it's not hard to imagine that if any were re-visited they'd also need to be updated visually. And the series trumps anything written in other media.
Like props, costumes and sets some aliens will need updating to meet modern standards and tastes too,
That said, the new series needs to establish its own identity first and not dig into existing continuity too much. Otherwise it risks alienating new audiences by giving too much fan service,
