I don't know about the Wave as I don't own one, but I'd suspect it's possible since it's two pieces. It just might be a snugger fit. The Flick however would probably not work. I have this case but no skin on my phone. It's one piece, and you need to slide the iPhone in. Not to mention it has two rubber strips on the inside of the back of the case to prevent scratches and hold it firmly in place. It's a snug enough fit already and I'd suspect it would damage the skin if you tried.
