Well, not really. When you got a story from the beginning, you have to follow it ever since it was made public. If you want to change something about the main villain, you're allowed to change something about him (Alex also changed Bill from green to yellow after all), and improve something to be better, but the overall basic storyline that defined the story wouldn't be able to change or it would contradicts the previous part. Imagine this: Now suddenly in the later half of FMA, it turns out that the villain is just a big fat guy wanted to be rich. Yeah nope, after all the build-up leading to his first appearance, that's not something we would want to see.

I agree that they might decide something would work better but the overall basic story wouldn't change, it's how it would be portrayed would change. The 2003 FMA changed the villain because it's essentially a "fan speculation" (I know it's not really, but it's the closest thing to compare) that was put on screen.
