I think the reason they talked about him being the new bond because Daniel Craig does not like playing bond. He has been hoping that each movie flops so he can terminate it early.
Now onto the topic. He is a good actor but I would not put him as bond simply for the reasons OP outlined. The character is already envisioned to be a white middle aged man with Scottish and British roots.
It is the same reason why you would not do a movie about a white samurai in Japan fighting against his former colleagues. Oh wait Hollywood did go there lol.
