the ca.165 had a very slim and small fuselage, but was heavier than the cr.42, which was due, arguably, to the different engine and construction. the caproni was not really a 'turning fighter', but given the limits of biplanes, was more of an 'energy fighter' with more pronounced capabilities in speed than turning (as was emphasized by the test pilots). an improved version was designed to address the maneuverability limitations, but the development was interrupted. it was built with non-strategic materials (steel and wood mainly), so it could have been at an advantage in the war in terms of strain on the materials industry, but given the type of engine, it is unclear if it was an economically practical aircraft.
