Can I sub the top crust for a crumb topping?

An apple pie with a crumb topping is called a Pennsylvania Dutch apple pie. I'd recommend using a specific recipe for one (like this one from Serious Eats https://www.seriouseats.com/pennsylvania-dutch-apple-pie-recipe-8399305) because a recipe that's written to make the filling and crust be done at the same time won't work with a crumble topping, which cooks faster than a pie crust topping. The Serious Eats one pre-cooks the apple filling to get around this.
