I am after the same thing, I use markdown + pandoc for myself but I think there is a real market for a simplified word processor like you're describing that can use complex templates. Think of like a business where they want people to use a standard format (font, heading, margins). It's all too easy to fuck those things up in word just by misclicking something when all you want to do is write and use a standard template.
