It's highly improbable, at least in foreseeable future. Saudia would rather hire from outside than promote expats within its ranks. The only case you may be upgraded is equipment phase out.
Things may change with local pilots upgrade policy change or management change. But for now it's like this.
Regarding kidnapping, it's something weird. I have never heard about it. First, there are no details at all. Second, it may happen in any country. Don't take it at face value.
