Your solution will not work for a variety of reasons. The Palestinians had their chance at a contiguous state in 1947, (and Israel was supposed to be the non contiguous state then, and they agreed), but they turned it down. f they do not abandon their dream pf "Palestine from the Sea to the River" they will simply end up having no state. In time, they will be dispersed in the rest of the crescent and have a single Palestinian state (instead of two), Jordan (70% Palestinian).
