I would see no problem with this. This collection of articles will tell you everything that you need to know about these: https://www.gardeningknowhow.com/edible/fruits/elderberry/

Sambucus canadensis survives up to 8,000 feet. One resource I checked said 10,000. It does need moisture to do well. Red elderberry, Sambucus racemosa, might grow at higher elevations but all parts of the plant are toxic.
