Forsworn, witches, Vampires and Werewolves would, in my opinion, make good bandit replacements. Being able to hire necromancers would add a little extra to gameplay, but there should be some penalty for doing so. I don't think the Bard's College would be a good faction per se because they don't really have a military, but the bards could mention that they're members of the Bard's College. The Dawnguard could function as high level quest givers that offer better rewards than most others. I agree that the Silver Hand would be a good faction to add, they could be made into a rival faction of the companions. As for the Thalmoor, I think that they would be best as an "emergent" faction: only having a military presence in the game after a certain amount of time passes.
