fe4 Genealogy of the holy war and fates story swap

[Jathan]

Ok so hear me out what if fire emblem genealogy of the holy war and fire emblem fates revelations had a story swap so imagine Sigurd and seliph and anankos and corrin having game swap thus anankos would be the protagonist of the first gen and Sigurd would have been the antagonist and Julia and azura image that swapped and not to forget mikoto and deirdre imagine how the story would be if swapped so in other like role swap with a different fire emblem game would it be amazing or no ? What would the game be called because of the swap what class for corrin ? Or seliph ? How would the relationship between fathers and their children be like ? How would deirdre be if she was in mikoto's position or Julia in azura's position in fact would seliph be adopted by a royal family like corrin being adopted by nohr family ? What story would you guys imagine in this position would it be a good fanfic story
