Spinning on that dizzy edge

So romanticalgirl was posting her responses to a random 5 things request, and to my prompt of "Five jobs Helo would have in an AU", she listed one as "Police Officer".

I'm reading Terry Pratchett's "The Fifth Elephant" right now.

My brain mashed up the two and came out with: BSG done as a Discworld AU. Specifically, the City Watch.

Vimes = Admiral Adama
Carrot = Helo
Angua = Athena
Colon = Colonel Tigh
Sybil = Roslin (at least the early, not-politically-savvy version)
Vetinari = Baltar, or possibly Romo Lampkin.

I'd have to let my brain spin a while for how to slot in the Cylons (I'm leaning towards the various baddies in Uberwald), Starbuck (one of the younger Lancre witches?), Apollo (tempted to cast him as a dwarf, because *hurr*hurr* Jamie Bamber is on the shorter side), Chief Tyrol (a wizard?)...dear god, BSG has a lot of characters.

What say you all?

ETA: The husband liked this game, too, and we came up with more, in addition to or in place of samwize's suggestions below.

Verence II = Apollo
Magrat = Dualla
Shawn Ogg = Billy
Agnes/Perdita = Boomer (with a head!Boomer)
Cheery Littlebottom = Racetrack
Mrs. Rosie Palm = Tory
Nobby = Hotdog
Granny Weatherwax = Elosha (shame about the dying thing)
Mrs. Cake = Deanna Biers (Three)
Jason Ogg = Sam Anders
