I was wondering about Brazil too. Their commitment to WWII was certainly enough to merit being considered as one of the more influential Allied nations, and they'd help round out the international flavor of the Security Council's makeup.
Unfortunately, at that time it was a country with a population by largely rural and illiterate, with an economy focused in the exportation of commodities, a traditionally isolationist foreign policy interspersed with sporadic automatic alignments against "disturbing elements of peace and international trade", without an infrastructure in industry, health, and educational systems that could serve as material and human support to the war effort that a World War required...
