Many of the SOs I know who landed jobs elsewhere had to augment their CV with some sort of past experience in addition to their P2X hours. Not saying it's not possible, but options are severely constrained with P2X alone, which unfortunately is by design. Even in places like Aus, where cruise hours straight go to the copilot column, employers will still look to see what kind of flying one actually did, and cruise hours are less competitive compared to actual P1 and and P2 hours.
