Let's just think about the Sunwalkers. They would need to create 3 specializations, create new spells, new animations, new talents, new glyphs, new armor, add class trainers in every city for convenience's sake, add 3 more artifacts, an other class hall, another class campaign, more class quests... They'd have to find some gimmick to make them unique, and on top of that it would be even more difficult to balance classes.
It's a lot of work for something that most players would ultimately call lazy, because it would inevitably be too similar to Paladins. They could definitely change some spells' names and visuals to give more racial flavors (like how Blood Elves used to have Seal of Blood rather than Seal of the Martyr in BC), but making separate classes for each race would not be a smart way to go about it.
