If the Axis evacuated North Africa in late 1942

How successful could an Axis evacuation from North Africa be in late 1942, and what would follow in the Mediterranean?

Most troops could escape, but the Allies would gain the coast, reopen Mediterranean transit, and might move against Sicily earlier.

An Axis withdrawal while the Mediterranean remained contested could get most of the force out. The Allies would gain the North African coast and reopen a rapid Mediterranean transit route toward the Far East. Aircraft could patrol along that coast to support the passage. If the withdrawal removed the need for Operation Torch, its forces could be redirected into a version of Operation Husky against Sicily. The proposed timing is loose, so this remains a conditional sequence rather than a dated alternative campaign plan.
