This is more of a side project that I might attempt (however unlikely due to life being unpredictable), but here's a few ideas for assets & structures commonly seen across the prairies & plains of Canada & the United States (and occasionally mexico):
Farmer cooperatives & grain elevators: There are large concrete grain elevators available for TPF2, but what doesn't exist yet are smaller facilities. In modern times, these are usually complexes of metal silos, but for most of the 19th & 20th century grain was handled in wooden buildings. Thousands were built (somewhere around 30 000 in Canada alone), and although most are out of service or demolished, they're still a common sight in smaller towns.

Barns: Ingo has already made some great assets for these, but I haven't found traditional barns with the characteristic barn roof.

False-front businesses: Usually built from 1 to 3 stories, many of these buildings have false fronts with the appearance of a grand facade, disguising a more ordinary structure in the back
