I don't really see it happening, since Fire Emblem has a bit more gameplay "depth" than Mario. The only way I can really see it happening is as a basic map maker where you design the layout of the map, place enemy soldiers on there, and decide certain unit types that can be used for the stage and the placement of the units. Though even that would be complicated, because you would have to decide what items and weapons the characters have, what their stats are, etc.
