An independent Palestinian state could be established, with the goodwill of other Muslim states, using the West Bank and incorporating a section of Jordan. That way the state would be whole, instead of split between two locations with a hostile nation in between.
But Jordan would have to be willing to share with the Palestinians. Which should have happened when the West Bank was under Jordan’s control.
’In 1947 the UN General Assembly recommended that the area that became the West Bank become part of a future Arab state, but this proposal was opposed by the Arab states at the time. In 1948, Jordan occupied the West Bank and annexed it in 1950.’ Wikipedia
