If I might provide my own opinion, I think they would do pretty good for themselves. Assuming Cleopatra brings her gold they'll be able pay their way to upper society, to say nothing of her royal blood. I'm sure the fact that she's queen of Egypt will look good to the local nobles, and maybe even the king might be open to a marriage allience between their children, as a way to make a future claim against Rome. In many ways I think it would be like when the Sassanids fled to China, just without the massive cultural gap between the elites.
