Yes, farm equippment should be good (and if I find a converted and skinned downed CIS Seismic Tank from the Clone Wars cartoon, I would do a map that takes place in the wreckage of that weapon); some civic speeders and transports would be good too (and they could have flying props to background too); some downed ships, cannons, etc... EDIT: Ah, industry props would be good too, since we can't exactly reproduce things like The Works, or some polluted by industries places (generally I use some Space Stations hardpoints, or props with clones in different scales - everything that comes in mind )...
