Or you could go South American, lots of Napoleonic looking uniforms, and some Napoleonic veterans occasionally.
Simon Bolivar etc, but you could use it as an excuse for an "imagi-nations" setting - the 18th century crowd do a lot of minor "German" states that are fictional for SYW bashes, so maybe you could opt for an 1820s South American imagi-nations setting if you can't find actual ones that match what you are looking for.
