The person behind www.pixellab.ai has been trying to make a SaaS out of that idea for about 2 years already and it just isn't there, the examples in the homepage are extremely cherry-picked, I bet most of their paying customers just use it as a starting point and then spend hours manually fix the sprites, which may be more than enough value for $12 a month and that's great but what is shows is that we are not as close as one would like to imagine, the "one leg in front of the other at about the same depth and the same color" is still problematic to this day; if most pants in the world had a different color for each leg I bet most of its animation issues would be solved, unfortunately we don't and most of the training data involves single-color pants/legs.
