No.
Ronaldo is not fit enough anymore and R Carlos is too old. They WERE two of the best players in the world but not now. It is extremely unlikely that Dunga will pick either of them especially since he hasnt used either since he became Brazil manager. With 6 months to go to the World Cup and no competitive international match until then, Dunga is not going to all of a sudden say 'oh i think ill pick Ronaldo and R Carlos for my WC squad even though neither has played under my tactics and methods before" . he will pick players from what he selcted already in qualification and recent friendlies so your talking about 23 players from the following:
Goalkeepers: Julio Cesar, Doni, Victor, Helton, Gomes
Defenders: Lucio, Juan, Thiago Silva, Luisao, Miranda, Andre Santos, Filipe Luis, , Marcelo, Kleber, Alex, Adriano, Maicon, Bastos, Dani Alves, Cris, Naldo, F Aurelio.
Midfielders: Kaka, G Silva, Josue, Felipe Melo, Diego, Elano, Lucas Leiva, Fabio Simplicio, Alex, Julio Baptista, Carlos Eduardo, Ramires, Sandro, Diego Souze, Kleberson, Anderson,
Forwards: Robinho, Luis Fabiano, Nilmar, Hulk, Diego Tardelli, Pato, Adriano
