I think the buttons and fingerprint reader will be fine because there is a hole on the side of the grip. The grip itself could turn out badly but we will see. In case it will block the screen from opening I will just shave away the top of it or something. A bit expensive for an experiment but I want a case with the least amount of DIY modifications.
I found similar cases but their grip didn't have a hole and I figured I would just break those trying to make a hole.
