Actors for 'new' characters? (spoilers for Legacy...)

Hey everyone! So I remember years (maybe?) back, there were some threads about who could play which characters from the various books and comics. There are a few threads now about what you'd want to see official illustrations and such, but I was curious who you all think could portray some of the more recent featured characters.

While the new Jacen covers are alright, both Jacen and Jaina still seem pretty generic to me, and so does Ben so far. Cade and Kol have pretty distinct looks, and I think they did a good job on that. It'd be interesting to see who could play the older Hett/Krayt and who could play the younger version. You can argue about the actors for the prequels but the Ewan/Alec worked for me. Some other random ones that would be interesting to see would be Dass Jennir and Darth Nihl, definately have interesting looks. Anyone have any ideas?
