Could an amphibious threat have unhinged Italy?

Could stronger Austro-Hungarian army-navy cooperation have turned naval strength into an amphibious threat against Italy?

Possibly: coastal landings might have forced Italy to abandon positions in the Alps, but the plan depended on scarce troops, coal, coordination, and sustained sea control.

A shortage of troops and coal, together with poor army-navy coordination, constrained any Austro-Hungarian amphibious plan. One possible concept used two landings: a northern blocking force supported by naval gunfire and a main landing south of Rome. If Italy abandoned the Alpine front to defend the capital, Austro-Hungarian land forces might then advance from the northeast. Ravenna was suggested as a northern objective because its capture would cut a major rail link between central and northern Italy. The plan remained contingent on scarce troops, coal, coordination, geography, and sustained sea control.
