I like your scenario.
Some annoying know-it-all may point out that dromedary camels seem not to have been widely used as mounts and beasts of burden until after about 1000 BC. I could email you a paper on the subject, if you like, and then you can know-it-all too.
New Kingdom/Mycenaean era Shasu, c.1200 BC, would still be walking, and packing their gear on donkeys. Or you could set the scenario a few hundred years later, when the Shasu have got camels, and make your raiders Dark Age Greeks. Or you could ignore me. It’s all good.
You'll shoot your eye out, kid!
