A plausible two unique unit mod for AOE2 Age of Conquerors (Revamped)

The possibility of such a mod has been going on in my head for a while now. Although it's true that the Forgotten Empires, African Kingdoms and Rise of Rajas expansions added a lot of new civs, I feel that many of them are similar to one another and don't offer much variety. My proposal is to make a mod for the original AOC expansion, refining the existing civs so that every civ now has two unique units, and adding a couple of new civs (the new civs too would have two unique units). Some of the new civs may have been already featured in the DLC expansions, but here they're given different units, hence are rather distinct from the DLC ones.

Annamese (new civ)

Elephant Skirmisher: trained at the castle, skirmisher mounted on the back of an elephant, deals bonus damage against archers and cavalry archers.

Mong Dong: trained at the dock, a medium-sized warship that fires bullet balls like a hand-cannoneer, and has bonus damage against fire ships and demo ships.

Annamese would also get the Water Palisade, which is a type of palisade that can only be built on water, and has the same stats as its land counterpart. And to build these things, they also get a ship called builder ship, which is dedicated to construct these palisades.

Aztecs

Existing Unique Unit: Jaguar Warrior

New Unit: Coyote Runner (taking from aoe3), trained at the barracks, fast infantry that has a bonus attack against villagers and buildings, excellent raiding unit.

New Unit: Heavy Axeman (it is said that the Anglo-Saxons deployed them during the battle of Hastings in 1066), trained at the barracks, slow-moving heavy infantry wielding a double-handed battle axe, deals bonus damage against both cavalry and infantry, and can chop down trees to make a pathway.

Byzantines

Existing: Cataphract

New: Ballista, trained at the siege workshop, kind of like a cross between a scorpion and a mangonel, launches an arrow-like projectile like the scorpion, but the projectile travels in an arch like the mangonel. Deals bonus damage against buildings, walls, and siege units.

Mapuche (new civ; the only native civ that has access to stable and to bombard cannon)

Mapuche Lancer: Trained at their stable. It's the only unit available in their stable, functions like the scout cavalry of generic civs. It deals bonus damage against other scout units (that is to say against scout cavalry, eagle warrior, maori warrior, and iroquois forest prowler).

Ironwood Club: Trained at their castle. Heavy infantryman wielding a long hardwood club, deals bonus damage against cavalry and buildings.

Mayans

Existing: Plumed Archers
