What would you want in a Days remake?

I would want them to include Roxas having the ability to summon Samurai as a gameplay mechanic instead of just something that's used in like one cutscene. And I think a Days remake would be a good opportunity to repackage the new lore, especially the stuff from the phone games which a large portion of the fandom wouldn't even be aware of. Such as include info about Elrena's old life with Maleficent, a bigger splash of Ventus, Subject X, etc.
