I'd look into some of the 28mm historical wargames producers. After a little bit of searching, Wargames Factory (
http://www.wargamesfactory.com/webstore) seems to fit really well with what you are imagining. Their Saxon line of plastics, combined with some Empire bits for guns and other weapons, would be pretty cool. Actually, looking at them, I think I may use their War of Spanish Succession guys in the future, when I'm working on my Empire force.
