As a fan of The His Dark Materials Trilogy I write an article about my dream cast for any adaptation: http://www.entertainmentfuse.com/dream-casting-dark-materials-trilogy/
I hope you enjoy.

Rachel Weisz is a good choice, considering that Mrs Coulter was a brunette in the novels. However, I love Nicole Kidman so it would be difficult to see someone else in the role. But all in all, a great list for alternative casting! Well done! :)
shareWhile I share your enthusiasm for the books and for the potential of a BBC miniseries, a list of your favorite actors seems like the least interesting angle you could've taken.
When fans start "dream casting," it tends to be unimaginative, and boring, and somehow a little creepy. Also, your 'cast' is consistent with only about 60% of the books' descriptions.
