1. Looks incredibly generic. Unless there is some deep plot already existing, pass. It looks like......well, a robot fighting insects. With that much editing you'd think there would be something more, even a clip from the opening or something.
2. The director of FMA wasn't exactly "talented" tbh. If you've read the manga, most everything happened scene for scene, which is cool, just not something that takes a great director or anything for. If anything the team would be better.
3. Gen Urobuchi......... I like the guy, just not everything he does. His work on Gargantia and Psycho Pass was rather weak, and Madoka, while good, would have been utter shit without the animation team.
