OOC : Why not use the levels of the other WiR? Perhaps with some adjustments...
I have some more info on Brazil, mostly about possible army and navy levels :
The army sucked, should be at the same level as the other south americans, soldiers were not well-paid and the training was nowhere near the desirable, only thing keeping it together was the very loyal leadership, with some skilled (for South America) commanders. Best army on South America was the Paraguayan AFAIK
The navy however was modern, and if he tries to do it he will probably manage to have capacity to build ironclads by 1864 or 65, like OTL Brazil :p
And the territory of the current state of Acre (and a small strip of land to its east) was owned by Bolivia, however, the area was barely populated...Maybe a map change won't be worth the trouble, but if you desire i can provide a map.
If you need help about Brazil feel free to ask and i can try to help
