In regards to changing the ethnicity of Superman:
I think it would thematically make sense for Superman to be Latino because he is the ultimate immigrant - he's practically a Dreamer. If they got someone like Oscar Isaac to play Superman, that would work perfectly.
Additionally, Post Crisis Lex Luthor is based on Donald Trump, so if you wanted to be really on the nose, you could have Lex run for president, and hate immigrants like Superman.
I think it would be great to make the Superman movie a analogy for the immigrant story and hire a mostly Latino crew to make it (imagine a Guillermo del Toro directed Superman movie). The film could be like DC's version of Black Panther and maybe show a good portion of this world that immigrants are not bad people...
