Well, perhaps on a basic level, yeah.
I could go with a basic 'musketeer, grenadier, lifeguards, light' format, but I'd hope there would be different subtypes. Perhaps based on more famous regiments. Young, middle and old guards for the French, Lieb Guards, Pavlovsk grenadiers for the Russians, Footguard and Rifles for the Brits, etc. etc.

It'd be nice to see some less well known units as well. Princessa Grenadiers for the Spanish. Terrible uniform (mmm, purple and white), wussy name, some of the most utterly badass men in the Spanish army :P
