Why a fast land aircraft still needed major work for carrier service

What besides speed and armament might have made the Mosquito useful as a carrier aircraft?

Its two-person crew was useful, but successful conversion required major reinforcement of the landing gear and airframe.

The Mosquito's speed, weapons, and two-person crew offered useful qualities for naval operations. Those advantages did not make a land aircraft ready for deck service. Carrier landings placed heavy loads on the undercarriage and surrounding airframe, requiring substantial reinforcement. Navalizing the aircraft required a structural engineering project far beyond adding an arrestor hook and a naval designation.
