I hope not.
I'm not the biggest fan of the name dropping nostalgia. Sure it's "cool" to pick a random famous or known name and then drop in a character and say "oh look it's them".
But it's not.
Sure you can go on forever on how "people change over time".......but if your showing us a younger "version of the character", then it's not really the character. With just Spock alone they have added a massive lore dumb of stuff....well, that just "does not exist". So everything they might do with "young Spock" is great...but it has nothing to do with the older "real" Spock. And it does not matter....they can't even "really" do anything....because Spock is officially like X and has the future history of X. So sure they can write a whole story where Spock meets a Vulcan guy, gets married and has twelve kids......but then they also have to "erase that from history" so it never gets mentioned...as it DOES never get mentioned.
And you get the weird things like Uhura "loves" her SNW crew........but totally dumps them in a couple years and utterly forgets about them and becomes part of Kirk's Crew and never looks back. And it's just odd that if Uhura "loves" Pike so much as the Greatest Captain Ever.....wonder why see did not go see him in the Menagerie episode? Not even a ten second "Captain Pike, good to see you again sir". But that did not happen.
I would much more like to see new original characters.
