Summary
An alternate universe, where Hohenheim intentionally made himself immortal and created the homunculi, while Father was the victim that finds a family.
Soon, his sons are on a quest to get their original bodies back, but discover a far more sinister plot on the way.
Imagine an alternate universe, where every character is changed. I, myself, had a challenge to do so. Yet, I believe I have a suitable cast swapping:
Envy plays Ed, Ed plays Greed, Greed plays Ling, Ling plays Gluttony, Gluttony plays Jean Havoc and Vato Falman, Falman plays Yoki, Yoki plays Maes Hughes, Hughes plays Kimblee, Kimblee plays Roy Mustang, Mustang plays Lust, Lust plays Riza Hawkeye, Hawkeye plays Wrath, Wrath plays Izumi Curtis, Izumi plays Olivier, Olivier plays Pride, Pride plays Alphonse, Alphonse plays Envy.
I will choose not to spoil the rest, but I think that takes care of the vital cast. -

Summary
Father makes more and more human-based homunculi, but he didn’t count on one crucial detail: it’s far harder to take the humanity out of them.
Especially when you make homunculi out of Maes Hughes, Riza Hawkeye and Roy Mustang.
