I was with you until this part.Because if the answer to either of those is no then if you use D&D magic you aren't playing a 100 years war game, you're playing a D&D/100 years war mash-up which looks a lot like D&D with a coat of 100 years war paint over the top.
Not true at all. You’d simply be playing a 100 years war game in which the populace doesn’t know how magic works, or one in which magic works differently from how people thought it did irl. Nothing about that makes it any less of a 100 Years War game.
