I guess Warspite could be another, since she's got a chair.
They could always add more Swedish shipgirls, like Fylgia and Gustav V.
Or even Tre Kronor and Göta Lejon if they're willing to include ships that were still under construction when WW2 ended. Seeing as we've already got Graf Zeppelin and Aquila (technically "still under construction" since work on them halted) I don't see why not.
