During the 1920s the Brazilian Government funded the construction of nine ships of this general design to be operated by Brazilian flag firms in coastal and regional trade. They were built in several European yards, as noted below. Most of them lasted until the 1960s.

I do not know whether Brazil pursued construction of these in WW; that would be up to TheCanadian. But I think that they would make a nice addition to the Brazilian merchant marine.

Ararangua class Brazilian Coastal Passenger Cargo Ship laid down 1926

Displacement: 3,560 t light; 3,731 t standard; 8,548 t normal; 12,402 t full load

Machinery: 129 tons, 1.5 %
Hull, fittings & equipment: 2,031 tons, 23.8 %
Fuel, ammunition & stores: 4,988 tons, 58.4 %
Miscellaneous weights: 1,400 tons, 16.4 %

Overall survivability and seakeeping ability:

Survivability (Non-critical penetrating hits needed to sink ship): 3,924 lbs/1,780 kg = 36.3x6”/152mm shells or .74 torpedoes
Stability (Unstable if below 1.00): 1.12
Metacentric height 2.3 ft / 0.7 m
Roll period: 14.3 seconds
Steadiness - As gun platform (Average = 50 %): 100 %
- Recoil effect (Restricted arc if above 1.00): 0.00
Seaboat quality (Average = 1.00): 2.00

Hull form characteristics:

Hull has a flush deck
Block coefficient: 0.650
Length to Beam Ratio: 6.87: 1
'Natural speed' for length: 18.94 kts
Power going to wave formation at top speed: 36 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 5.00 degrees
Stern overhang: 9.84 ft / 3.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 32.81 ft / 10.00 m
- Forecastle (10 %): 29.53 ft / 9.00 m
- Mid (50 %): 21.33 ft / 6.50 m
- Quarterdeck (5 %): 21.33 ft / 6.50 m
- Stern: 29.53 ft / 9.00 m
- Average freeboard: 24.12 ft / 7.35 m

Ship space, strength and comments:

Space - Hull below water (magazines/engines, low = better): 24.4 %
- Above water (accommodation/working, high = better): 143.3 %
Waterplane Area: 14,330 Square feet or 1,331 Square metres
Displacement factor (Displacement / loading): 515 %
Structure weight / hull surface area: 69 lbs/sq ft or 339 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.83
- Longitudinal: 5.30
- Overall: 1.00
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, rides out heavy weather easily

Low-stowed cargo simmed as additional bunkers. Normal radius 10,000 nm at 12 knots - bunkers = 735 tons. Total cargo 4,000 tons.

Breakdown of miscellaneous weight

Provision for cargo-handling gear - 200 tons
Provision for cabin passengers and amenities - 800 tons (300 cabin passengers plus public spaces)
Provision for deck passengers - 400 tons (up to 600 deck passengers for short coastal voyages)

Crew complement and survivability reduced for commercial service

I can't see any reason why they wouldn't have been built to be honest. Mind you that would have been before my time running Brazil.
