I suspect that the Israelis would have been handed their heads (or their arses) and the Egyptians and Syrians been encouraged to renew their efforts (they had only committed relatively small forces). The Israeli faction that wanted more war was also the faction that pushed for independence (five cabinet members had voted against) and the "doves" were all Sabras and not so close to external influences. The Western powers at the time (including the US) regarded the Provisional Israeli Government as too close to Moscow and further breaches of cease-fire agreements may well have lost US sympathy (they already had none with Britain).
Also, it's quite interesting that your thoughts on this are quite different from @starman's thoughts on this in another thread. Starman said that he believes that Israel would have conquered half of the West Bank had it indeed launched this attack.
