A simple but dauting Challenge: change the Portuguese colonization of Brasil to a Spanish one and have a Spanish-speaking Brasil (for all that skipped the Geography classes: Brasil DOES NOT SPEAK SPANISH, BUT PORTUGUESE....lol)
Only a rule:
1- Brasil OTL Territory should be preserved in the "Spanish Brasil" (so, keep Brasil as one country, differently of what happened in the Spanish Latin America Colonies).
If possible, try to keep the Brazilian OTL cultural aspects: it would be fun to hear Chica de Ipanema instead of Garota de Ipanema...
