I forgot about the flags!
How about standard samurais as Dao phalanx, but with flags on their backs. I do not think the falgs are good for the archers...

I would be tempted to add the falgs for knights too, but already decided to go with the mongollian units (mongolian mounted swordsman from warlords scenarios|for the knight). Nothing stops me from giving them some kind of wings or even flags, just not sure it fits.
For immortal, I think I will add one of HoTK heroes, one with green dress and spear - just need to rebone him to phalanx and give him a nice shield (or should I skip the shield?)
For now I do not plan more asian civs, and already decided that chinese hand cannon & hwacha will be in as unique units for Dao. But will try to add some nice ships models
As this is an art post, one more thing.
I am not content with doa howitzer art. First, it is not howitzer. Second, it is just medieval cannon - does not fit mechanos that well.
Designing the unit, I thought of vinci steam cannon from rise of legends. If you did not play that game, here is concept art for the cannon:

So, I want a change. How about the attached unit? I quite like it, but some of you might find it too modern, so decided to ask first.
Also, take look at the copters - would you accept any of them in game as mechanos airship replacement?
I have choosen the ones that fits mechanos the best IMHO, plus I can do some repainting, but the shape will not change. So please, tell me what you think.
