Apparently the original thread on this topic deteriorated, but I thought the idea was intriguing. As I recall the premise was that Hitler wired Mussolini prior to their October 28, 1940 meeting (the one at which Il Duce announced "Fuhrer, we are on the march!"), persuaded him to hold off until they could meet, and then persuaded him to forego the invasion of Greece. Everything up to that point happens as it did historically, the invasion force in Albania is primed to go, followon echelons in Italy are preparing to deploy, and the army in Libya has advanced to the Sidi Barrani area and dug in in its series of fortified camps. That army comprised almost entirely infantry, so the first big change is to reinforce it with armored units. The only armor present is two battalions detached from the Ariete armored division and assigned to the Maletti motorized group; they are equipped with M11/39 medium tanks (hull-mounted 37mm gun) and L3 lights (MGs only). Incidentally Italy's entire inventory of M11s is in North (72) or East Africa (24). Historically two more Ariete battalions would be attached to the Babini Group in Cyrenaica, so the first step in our scenario might be to station the entire Ariete there, to be followed by other divisions as time and shipping permit. The newer M13/40, the first Italian tank comparable to the British cruisers, was just coming into service. A few of them were in Bardia before it was invested by the British in late December 1940, but they were first used in numbers at Mechili and famously at Beda Fomm, where approximately 101 were in action against British forces including 29 cruisers. Historically M13s also served with the Centauro Division in Greece, so presumably more of them would have been present in Cyrenaica in our scenario. It seems unlikely that useful reinforcements, including M13s, would arrive in Egypt in time to stymie the initial Operation Compass offensive, but the subsequent British advance might have to contend with 1-2 Italian armored divisions, presumably under Italy's most capable commanders.
