propogation

Hi Y'all, I am in my 3rd year of growing out potted trees so I can eventually develop them into bonsai. In place of purchasing further stock, I would like to begin propagating via cuttings and air layering. To start, I would like to try my hand with my yoshino and weeping yoshino cherries...

Is it likely that I can propagate this Pyracantha by taking these two large branches as cuttings? I've successfully taken cuttings of a similar size from an olive. But I'm not sure how comparable a Pyracantha is/how easily they root.
