But beyond that, it's very hard to cast, because there are so many possibilities!
One could have Envy cast as the Six-Fingered Man, for the joy of watching Roy confront him ("My name is Roy Mustang. You killed my best friend. Prepare to die."), or you could cast him as Prince Humperdinck for the equally awesome joy of having Ed challenge him to a duel to the pain and him wimping out.
You could cast Greed as Vizzini, but that really works better if you then make at least some of his gang Inigo and Fezzik, which means probably casting Martel as Inigo, which would then make Kimbley the Six-Fingered Man. ("My name is Martel. You betrayed my friends. Prepare to die.")
And what to use for the equivalent to the Dread Pirate Roberts? I am, of course, tempted to make it the Dread Pirate Fullmetal. But maybe I'm just cheesy by nature.
Then, naturally, you could cast Armstrong as the Impressive Clergyman, which would result in him looming over Winry and whoever the heck you cast as Humperdinck (I like the mental image of a very bored and irritated Envy), intoning "MARRIAGE! MARRIAGE IS WHAT BRINGS US TOGETHER TODAY! MARRIAGE, THAT BLESSED UNION, PASSED DOWN IN MY MONASTERY FOR GENERATIONS!"
And then there's the sheer fun of imagining Roy and Ed pushing a flaming Alphonse toward a crowd of screaming, fleeing palace guards, as the armorboy does his best attempt to sound scary. "I am the dread pirate Fullmetal! There will be no survivors! My men are here, and I am here, but soon you will not be here!"
And of course the idea of Winry and Ed navigating the fire swamp is completely rich. You just know Winry would be pounding the brains out of those ROUSes with that branch, nevermind Buttercup's terrified canon behavior. It was, after all, his right shoulder that got attacked. Nobody messes with the automail.
And...you know what, I think you get the idea. FMA needs to be crossed over with Princess Bride. Desperately. End of story. <3

<3 The EdWin 100 Themes <3 She remembers the way her inexplicably riveted gaze slid unbidden down the curves of his back, slowly, like honey. And she particularly remembers the rush of prickly heat, the unfamiliar melting sensation that made her duck her head to hide a blush that caught her entirely by surprise; as she realized for the first time, in an entirely new way, that Ed was a boy.
