BSG meets HDM + Buffy meme

So I'm re-reading His Dark Materials for the millionth time, and I started mentally casting the BSG peeps in the Pullman roles.  Here's what I've got so far:

Lyra = Kara (obviously)
Will = Lee (the stuff with his mom is just too appropriate)
Roger = Helo (*sniff* poor Helo)
Lord Asriel = Lord Adama
Mrs. Coulter = Admiral Cain, or possibly Number Six.  She's a bit tricky.

And here's where I run into trouble.  I mean, Iorek is Iorek.  I just can't imagine any of the BSG characters as bears.  Perhaps Laura Roslin as Serafina?  Should she be Mary Malone?  Maybe Athena is Serafina and Laura is Mary.  And what about Lee Scoresby?  Or am I just crazy?

Now, Buffy meme!  I skipped a couple days so I'm gonna do two.
