2 words: stardew valley.
Ed and Al take the place of Haley and Emily in the sense that they're siblings in their twenties, they live together without parents, and Al is liked by everyone in town and Ed is uhhhh Not. Al would probably work at the Saloon like Emily does but isn't on his feet the whole time (he and Ed are still disabled-- Al has bad chronic pain and joint issues, Ed has a prosthetic leg.) I can see Ed being into photography the same way Haley is too.
Hohenheim is the father that returns randomly in year 3. Not much to say about that except that the town does not give him a warm reception on account of the whole abandoning your children thing. Maybe he fucks off soon after to live in the forest like the Wizard.
Pinako and Winry take Clint's place as the town blacksmiths because who needs that guy am I right. Winry's loved gifts would probably be raw materials and batteries.
Ling is like Elliott in that he lives on the beach and that is the end of the similarities. He has so much money (very obvious the way he talks about it) but he chooses to live in a repurposed fishing shack. In one of Ed's dialogues he speculates that Ling only lives there to scavenge for food like a seagull (he is right).
I think this goes without saying but Mustang would be the mayor. If you get enough hearts with him you get his tragic PTSD military backstory. I don't know what Hawkeye would be or where she would live in this situation, but I do know that she and Roy have the same weird secret relationship that Marnie and Lewis do.
