Suggestion for Cowboys:
New Troop: Lonesome Rider
Skills / Hp/ What armor : Unlike normal cowboys, has a horse. Can use pistol and a cavalry saber. Has a fast horse and a good ability to shoot from it. This class seems necessary to me, because what fun are cowboys if they are all on foot?
Suggestion for Chinese Dynasties:
New Troop: Artillerist
Skills / Hp / What armor : Has a big carriage in front with rockets coming from it. Uses a horse like some enemies (alien bug, rhinoceros), reskinned like the crusader carriage, but moves very slowly. Attacks slowly but deals area-of-effect damage like exploding melon, and with poor accuracy/reload speed.
Suggestion for 17th Century:
New Troop: Plantation Rebel
Skills / Hp / What armor : Has poor armour (basic clothes), but high-damage unwieldy worktool-weapons such as scythes, hammers, machetes and lumber axes. Has high strength, 2-handed skill, ironskin.
Suggestion for 7 Years War (and 7 Years War France/Britain)
New Troop: Native Ally
Skills / Hp / What armor : Has poor armour (use the one from the native invasions for a north american first nations person), high skill in throwing weapons and bows, and athletics. Has the option to use the muskets of their faction.
Suggestion for Gallic/Germanic
New Troop: Barbaric Warrior
Skills / Hp / What armor: Similar to the other Germanic warriors, but no shield and better access to heavy weapons and better skill with them (2-handed, pole).
Suggestions for Anglo-Zulu War
New Troop: Boer (see the original mod, they were quite a lot of fun to play)
New Troop: African ally
Skills/ Hp/ What armour: Borrow skins from the zulu invasion factions, give them access to the Martini-Henri rifle, and give them the full bodysuit / head from the zulu invasions, with additional shakos and redcoats if possible. Give them weaker skill with the rifle but better polearm skill so they are better on the charge. Offer throwing and native african weapons (from the zulu invasion faction) to have a sort of skirmisher to support the british.
