Only if Uncle Joe decides to groom him for a takeover after his own death, this would require a significant change in Stalin's own personality with regards to his succession and for him to admit that well... he was an old man in increasingly poor health and that some day he was going to go off to that great big collective farm in the sky so may as well pick out someone he likes.
This might possibly be accomplished by having Stalin live a little longer, but he may just as easily decide that Beria, along with Molotov and others, is old guard and needs to get the axe to make way for people like Malenkov and Khruschev (yes really), that is the most likely outcome of this "Doctor's Plot" that Stalin was cooking up, forget the pogrom, that wasn't Stalin's way, the Doctor's Plot was going be yet another installment in Uncle Joe's housecleaning plan for the communist party.
Beria's USSR would look very interesting, the man was a reformer, and he wanted to pal up with the West after the war... would have been interesting if he could have accomplished such a goal.
Also wanted to create Israel, hooray!
