Jason Statham as The Hitman instead of Timothy Olyphant.
To be honest, I'm not a huge Statham fan (despite loving the first Transporter, WAR, Chaos and his Guy Ritchie films).
A British badass like him would be too much for Agent 47. I always thought that a younger Bruce Willis could handle the role. Hell, how about Dolph Lundgren shave his head and play his own badass self? Then everyone's happy . . .
Well, I think Lucas can bring good ideas, but he must not be a part in the story. And for Director I will be happy if it was Paul Verhoeven who made the second trilogy.
While I'm not resistent to that, Paul would go over the top with the lightsaber battles and they were actually solidly done. Just get a good HK fight choreographer and stick with a veteran like Spielberg.
Nolan would be cool but too much I think.
