Aislinn's (and Golgfag's) settlement gifting mechanic would be perfect for DoW

Breaking out the copium again here, because after looking over how Aislinn works I'm seeing a lot that could be adapted for DoW.

Basically, DoW operate as mercenaries much like Golgfag, but they also own City-States, with a strong mercantile theme.

It could be set up that a DoW army, under contract, would attack an enemy settlement and then gift it to their patron. You would then get access to a special building chain within them, like Aislinn's, that lets you benefit from the settlement and how it's built up - basically you set up a little part of your corporate empire there.

The buildingchains could operate in various ways: by generating money from the existing income; allowing the recruitment of your units by them like Ogre Camps; or some other various bonuses (just look at how many different buildings Kislev can do, as an example). You could also have it so that one building at max level lets you buy the settlement outright, providing you with another city-state under your control.

The goal of DoW would be conquering the map - not by force, but by becoming the richest merchant company in the world!

And if this sounds a bit too Ordertide focused, don't forget that DoW also work often for the more evil races - and Ghazak Khan is a Hobgoblin LL who would be an ideal evil-focused option, though he'd have to exchange a lot of the Tilean themed units for the Hobgoblin roster I'd imagine.
