I dont know why people feel the need to change the James Bond character. The Bond franchise is a proven success commercially and changing race/gender of an already established main character rarely has box office success. It could work, but there are so many other stories to tell. Just to name a few: Alex Cross, Ezekiel Rawlins, or reboot Shaft; Red Sparrow, Kim Possible, or Laura Kroft for the ladies. The Bond formula can be to any of these.
