In 48, this "motley collection" put the Arab forces to shame-some of the Arab units were still armed with muzzleloaders, and they were outnumbered and disorganized. It wasn't even close, and anyone who looked at the relative state of the forces before the war (as America did) could obviously see what the outcome would be.
In 67, the egyptian air force was destroyed on the first day of battle. After that, it was again no military contest. The equipment wasn't even near the disparity needed to change the balances after Israel's surprise attack. Nasser was a moron who believed American promises that Israel would not attack him first.
Stating what the Israeli equipment was is meaningless unless you compare the Arab equipment-add it in to your scenario, and you'll see how ridiculous it is to talk about the outgunned Israelis. They were far ahead of their Arab counterparts.
If, in 1948, you count
each and every adult Jew in Israelas a combatant, yes they had "superior numbers" relative to the invading Arab armies. That is not a reasonable reading of the facts, though.
The military establishments of the various Arab states were not equipped with muzzle loaders. That would be local boys looking to shoot up some Jews for fun & profit.
Israeli equipment was piss-poor and they had no professional equivalent to the Arab Legion, a force equipped & trained to Brit standards (to include mech forces)
and led by Brit officers in 1948.
In contrast, during the 1948 war, Israel had a grand total of
14 operational M4 Sherman tanks it had salvaged from an Italian junkyard and re-gunned with 75mm Krupp guns, since the original guns had been demilled in anticipation of the tanks being sold for their scrap metal value.
The Sherman and its variants was the backbone of Israeli armor through the 1973 war, when they were destroyed in large numbers by Soviet Sagger ATGMs.
Meanwhile, in 1956 those Shermans squared off vs Egyptian Shermans equipped with a superior French AMX13 turret. In 1967, Israeli Shermans fought versus Soviet T34, T55, & T54 tanks manned by Egyptians, much superior to the Sherman (which was considered barely adequate for a WWII tank). On the other side of the country, the Shermans faced US-built M47 Patton tanks. In 1973, those Shermans face more T54/55 tanks, along with the even more advanced T62 tanks.
The arithmetic for capable combat aircraft was 2:1 against the Israelis at the start of the Six Day War
counting only Egyptian aircraft. Capable defined as contemporary jet fighters & medium bombers.
Sorry, no reasonable analysis can be made for the superiority in quantity or quality of Israeli equipment over their antagonists' until well after 1973.
