FE-bruary Hangover: Let's Remake FE4!

So. Now that we've established that IS will do remakes, and we have this shiny new system for pairing up characters and breedin' babies, how 'bout that Shin Seisen no Keifu?

This is partly tongue-in-cheek and partly a guesstimate based on what IS actually did with the Archanea remakes-- what they kept, what they changed, what they ignored.
