Could Brazil have operated two Riachuelo-class battleships?

How plausible was it for Brazil to operate two Riachuelo-class battleships after the Second World War?

It was technically plausible if Brazil maintained its infrastructure and supplied the money and political support.

The answer distinguishes technical feasibility from willingness to fund a battlefleet. Brazil already had infrastructure that could be maintained for large warships, so it would not be starting from nothing. With permission to pursue the programme and enough money, the navy faced no inherent obstacle to operating the ships. The central issue is sustained finance and authorization rather than whether the country could ever support them.
