P. wallichiana comes from the same area as P. roxburghii, but mostly at higher altitudes (rox: 400-2300m, wally: 1800-3400m, so there is some overlap), so adapted to a somewhat cooler climate, and probably more important, wetter climate. But certainly still well worth a try. Broadly the same altitudes as Cedrus deodara, but with more of a tendency to be on north-facing slopes, with the cedar on sunnier south-facing slopes.

P. geradiana and P. bungeana should both be rather more drought tolerant - they're very like pinyons.

Don't take too narrow a view of those species' tolerance to climatic conditions. For example, both deodar and chir pine do well in California, even though they live in a summer-rainfall climate, and California is a winter-rainfall area. It's fallacious to try to match climates with precision with the expectation of predicting a species' performance. Very rough approximation followed by empirical testing makes more sense. Take some chances.

Go for it. I just got one last year, doing OK in alkaline soil. Deodars do excellent around here, as well as my Chir pine
