Its far too late to make such a major change to the races. If a patch were focused on more customization within the races, I would be perfectly content with more options for what is already there (face, nose, eye, and body shapes, scars, tattoos, ear shapes for Elezen, tails for Miqo'te, etc, etc). Turning Roes into fish people and Miqo'te into any furry animal that's ever existed is too much of a change for the lore that has been established for more than six years and its a change I wouldn't welcome.
