Children and Family Films : Theoretical UK English Dubs of US Films

Theoretical UK English Dubs of US Films

If the Alvin and the Chipmunks films, per se, were dubbed in the UK with British actors/voice actors, who would dub who, do you think?

I assumed:
• Christian Bale as Dave (Jason Lee)
• Simon Pegg as Ian (David Cross)
• Emily Blunt as Zoe (Jenny Slate)
• Jennifer Saunders as Gail (Jane Lynch)
• Robbie Williams as Alvin (Justin Long)
• Daniel Radcliffe as Theodore (Jesse McCartney)
• Kate Thornton as Jillian Reynolds (Herself)

As for Claire (Cameron Richardson), Simon(e) (Matthew Grey Gubler/Alan Tudyk), Brittany (Christina Applegate), Jeanette (Anna Faris), Eleanor (Amy Poehler), Toby (Zachary Levi), Ryan (Kevin G. Schmidt), Xander (Chris Warren, Jr.), etc. I am COMPLETELY stumped. Any suggestions?

For that matter, who else would dub theoretical UK exclusive dubs to classic Disney films? Or any other US film which didn't get an exclusively British dub?
