I would be down with making the whole land a unique democratic state, free to anyone to vote or belief whatever they want like any democratic nation.
But I’m sorry to say that no side of the conflict seeks that. Not Hamas, not the Israeli government. Both just seek total extermination of the other side.
Most of current Palestine is not only Muslim, but also pretty radical about their beliefs, that’s just the way the cookie crumbles, there’s no sugar coating it.
I seek it. I’m one side in this too. There are many Palestinians and many Israelis who just want to have normal lives and full human rights for themselves and others.
I think you then might want to learn more about current Palestine, which is much more diverse than you describe.
