Thracia 776 is on my to-do list after I play through Shadows of Velentia. I'll keep that comment in mind.
But part of it is
rewriting. Elements of the story change, like L'Arachel not being the actual princess and just being distantly related. It would need several completely original maps to cover L'Arachel setting off with Dozla, meeting Rennac, and getting several of the FE8 units herself on her terms instead of them being in the Renais army. Then things would get to remixing existing maps when L'Arachel joins up with Eir/Eph.
>if you aren't shitposting
I'm almost shitposting because I don't expect myself to open Fire Emblem Builder or Lex Talionis and actually make this happen. Though I do plan to learn python anyway, and Lex Talionis uses that, so if the idea really got fleshed out, maybe?
Mostly it's fun to mull over the idea and wonder how it could be accomplished. Pie-in-the-sky for me.
