No.
As much as I liked The Origin, it was too predictable.
It basically followed the games and while I do like that type of loyalty, I far more enjoy the fact that our current anime strays so far from the games, introduces original characters, has anime original plots, etc. Granted, I can be often annoyed by how they skip some points from the games like the appearance of the the villains, but I enjoy current anime far too much for it to be replaced by another one. I wouldn't mind a second anime like The Origin airing next to it, but replace? No way. Plus, it would just make it horrible. We have been watching Ash battle for 16 years and for him to be suddenly replaced without any sort of conclusion to his journey would suck. I'd rather Ash was replaced by the next generation protagonist, rather than Red, if that ever happens.
Also, Red is overrated.
