I suggestion I made over in the Rogue Trade Apocalypse hack forum was that if you want a more abstracted resource thing, but want to keep some granularity for barter, you could make it "roll+barter risked" rather than "roll+barter spent".
The idea here is that barter is more like capital. If you hold onto it it provides an ongoing resource, but you can also liquidate it to have some instant cash. When you "risk" barter, you keep it if the roll is successful, but if its unsuccessful (or on a 7-9) maybe you lose some or all of the risked barter, or maybe it's just put into a compromising situation where you have to act to secure it. This makes a nice situation generation type move (oh, shit, the warlord raided my fields when I tried to strike a deal in hash! I have to save my weed farm!).
Personally, this feels different than straight up AW to me, more of a focus on building and maintaining things and larger scale economics, but I may use a variation of it in some of my hacks.
