Not really possible. Since for every Arab Palestinian that became a refugee in '48. A Levantine or North African Jew ended up in Israel, after being run out of where ever they were. And Palestinians out number Jewish Israelis (who make up 74.7 % of Israel's population) if you count the 5 million refugees in Jordan, Syria, Lebannon, and Saudi Arabia. The 1.8 million Arab Israelis* and the 4.5 million Palestinian population in the PNA territories.
Your one state B solution makes Jewish Israelis a minority in their homeland at a pen stroke. And you've replaced what we have now for second Lebannon. The person who could convince Jewish Israelis to go with this is either:
1. A dark wizard most powerful (possibly even a space wizard)
2. A literal god
3. A telepath stronger than Professor X or Jean Grey
*Who don't universally self identify as Palestinian to avoid Jewish discrimination.
