The postwar Seagull could fit battleship-scale aviation spaces

Could the postwar Supermarine Seagull fit aboard a King George V-class battleship?

Yes; it was intended for shipboard use and should fit aviation spaces comparable to those on large cruisers and battleships.

The Seagull should fit the relevant shipboard aviation spaces. The aircraft had been designed with operation from cruiser-scale ships such as the Baltimore class in mind. A battleship's hangar arrangement was therefore not inherently too small for the type. Aircraft dimensions still set practical limits on catapult-era shipboard aviation.
