I have a skin and a screen protector at the same time and yes it looks nice. Also. Using no heat and a pocket knife. I took off the front and back glass. Yes I cut my fingers. It is possible. Yes you can do it. Also I laughed when you asked if Apple sold parts. Steve Jobs made the first iPhone to stay locked in so no ones messes with anything in that case there’s no way they would sell parts you have to order replicas online. Not that they’re bad or anything. Some can be customized. It just takes what I did if you don’t have the big tools.
