There are some other games' miniatures that would work well with Dresden. Vampire the Masquerade figures of course, Shadowrun figures, and Reaper Miniatures have some good modern figs. It wouldn't be difficult to use many of the D&D monsters as baddies either, as the Dresden RPG powers list makes it a pretty easy conversion. I've even adapted many ideas from novels and films using this list, into easy Dresden templates...for example Immortals from Highlander, Vampires from different novels, Witches, Druids, even Simon Greene's Nightside series (which has some great Dresden-esque characters)....
