This is kind of off-topic, as Little Grizzly politely hinted, but I'm sorry, I can't resist. There are no protections you could put into the Consitution that the Palestinians wouldn't override on day 3. If they didn't have the votes, enough Jordanians, Syrians Lebanese, et. al. would enter the new secular state, register to vote, and swell the ranks until they had the votes, assuming folks like Hamas would waste their time with following Constitutions in the first place.
Any one-state solution means death/displacement to all Jews in Israel. Period.
