No, nothing will happen. The Saudi - Iran deal happened because both countries were facing strategic costs, and were about equal in strength when negotiating
In Israel's case, it doesn't face any big strategic costs for it to compromise with the Palestinians. Also, the balance of power is much much in favour to Israel.
To be frank, Israel would be dumb as rock to negotiate any deal with Palestine when it can just keep doing its salami slicing.
Some decades later and the Palestinian problem would be "solved" automatically
You are assuming that everything Israel did and has been doing so far is due to Israel being invincible. It is not, it is actually the US enabling. You are also assuming that US empire will last forever, and there is never a day when US is too weak to bother what happens to Israel.
The Israelis are far less confident than you. Therefor Israel has been trying to find backups since its establishment, be it EU or China or even Russia. Just tell you one thing about Israel. Israel recognized PRC on January 9th 1950 being the first country in the region, well before US and many European countries. Funny enough, ROC recognized Israel on March 1st 1949, but Israel turned that down even though PRC is not established yet. That explains how much security guarantee that Israel want, or how much trust they have on US (far from enough).
It would be stupid for any Israeli politician not preparing a place and compromise for the post-US world order in exchange for Arab's compromise and a new guarantor. The only able guarantor after US is China and China disagree with Israel's occupation of west bank. So China isn't going to stop Arabs in fighting for west bank or Syrians to fight for Golan height at the least.
I have twice asked Jewish people (Israeli and ethnic Jew) the questions "do you think US will be there for Israel forever? why not make a good deal when you still have the upper hand?". There was no answer but the expression of "what can we do?"
