A cool model? Yeah, sure.
This is a Star Wars miniatures game. All the other points you listed are basically irrelevant. It's cool, it's Star Wars, it's iconic and much loved, and it would fit in this scale. There's no reason NOT to release one.
Having said that, there's no reason an AT AT would need to be boring or difficult to use. It's footprint would not be significantly larger than that of Huge ships in X Wing, and it could use a similar movement system.
It could even feature stormtroopers rappelling down to deploy on the table.
