Yep. That’s a good way of turning Jordan from an ally into an enemy very quickly when the King gets overthrown just as the Shah was in Iran.
Egypt could probably absorb them though. They’ve got a population size large enough for it not to make much of an impact on their demographics.
That’s why Egypt is the only other country, along with Israel, that hasn’t got its US taxpayer largesse frozen. We’re funding the Greater Israel project.
