If there were a musical version of James Cameron's Titanic, who would you like to see cast?

Here's my list (you don't have to add all these characters:) ) :

Jack Dawson: Hadley Fraser
Rose DeWitt Bukater: Jennifer Damiano or Sierra Boggess
Caledon Hockley: Ramin Karimloo
Ruth DeWitt Bukater: Patti LuPone
Spicer Lovejoy: Terrence Mann
Fabrizio DeRossi: Max Krumm
Tommy Ryan: Jeremy Hayes
Helga Dahl: Katie Hall or Jenny Latimer
Molly Brown: Kathy Bates
Mr. Andrews: Victor Garber
Bruce Ismay: Gareth Snook
Captain Smith: Colm Wilkinson
Brock Lovett: Gary Mauer
Lizzy Calvert: Meredith Braun
Old Rose: Pippa Pertree (sp?)
Also, if they decided write Nathan Hockley into the musical rather than just being mentioned in passing, Billy Zane would be the perfect choice for that part.
