I would rather they leave The Menagerie alone. But I could see the temptation being too much for them not to overturn it. And they'll use the rationalization/excuse that TOS is over fifty years old, they are writing for today's audience that might not have even seen TOS or were born when it came out, or that this doesn't erase Menagerie from your DVD/Blu-Ray collection, and so forth.
While Pike is the main character on SNW, it's not just his series, IMO. While they can still keep the Menagerie, in which he does get something of a happy ending, we don't know the fates of most of the other characters, so there's lots of room to have multiple happy endings for them.
