I had always thought Katee Sackhoff would be a good Brienne, but I do think Gwen Christie's nine foot tallness adds a lot to the role, so maybe someone taller... it's one thing you can't quite fake.
Jennifer Wilson would probably make a good Brienne. 6 foot 2 and blonde. She looks kinda pretty but I'm sure they can ugly her up for the role (if they can make Charlize Theron look ugly I'm sure they can make anyone look ugly).
How about Jonathan Frakes (commander Riker) for Barristan Selmy, he's tall, blue-eyed, has a natural kindness in his features and is a believable tough guy despite being 60.
