[@Lucidnonsense]You could do a Mekhania expedition force.

I have some ideas how the noble courts work there (they are ridiculus) but if you do a standard troop commander, or perhaps a techno-arcanist. You could focus on clockwork troops.

Although considering how the Mekhania usually handles things, the only way to make the clockwork angels fly properly would be with magical jet-packs...
Also, the flying troops schtick is starting to get a bit common, so i'd suggest a ground based troop.

But otherwise, i guess it's more fun if you do your own thing. But i sort of stole the clockwork steampunk thingy and it would be a bit strange if several nations did it.
Just suggestions though, naturally GM has final say.
