Finn has one slot left and my kingdom for a Poe Dameron, please. Finn's from the end of TFA, so he's almost certainly missed the events of Last Jedi and a good chunk of the timeskip before Episode 9.
The Doctor has both of his slots left open for the moment, and frankly I'd love any past or present companions who might want to show up. His canon point was the end of series 1, but he's the Tenth Doctor now anyway because of intermission events, and loltimetravel anyway.
