Any Portuguese king that allowed that would be committing political suicide. it's would be as much truth in the XIX century as it was in the later middle ages over any piece of the mainland.
And a Brazilian king? If the Liberal Loyalist Enclave in the Azores has already been defeated by the Miguelites prior to Dom Pedro's expedition- perhaps even if Maria II herself has been imprisoned, or killed by Dom Miguel? In such a scenario, who's to say he wouldn't be going over there to reconquer Portugal and bring it under Brazilian rule? In such a scenario, he may well be open to creating a new Kingdom of Portugal in the Azores, in a similar manner to the Kingdom of the Algarves. The intention would be to create it merely as a symbolic title, but depending on how the war goes on the Portuguese mainland, it could well become something more, leaving the appointed 'King of the Azores' as the actual ruler over the islands for a considerable period of time.
