Those are pretty good choices. I especially love your choice for casting Iñaki Godoy as Beast Boy. Beast Boy has always been my favorite character, and after his incredible performance in One Piece, I also think he would be perfect for the role. BTW, just so you know, his name is pronounced In-Nya-Key Go-doy.
Nicely done. Cyborg is going to have to hit the gym… Thor style. All the Starfire picks are excellent. Starfire is going to have to be orange with bright solid green eyes, and they need to include a red-headed Wally West and a Wonder Girl as per the 80s line up. No need to race-swap or gender-swap, or preference swap. These were great characters with great stories on the page. Very well written with great chemistry and deep back stories. Could be a franchise if they do it right.
