i want to see what they look like
I’m not sure what you’re asking exactly. Since you can view all of the normal skins in the Command Center even without them being unlocked, I’m assuming you mean her “hidden” skins?
I’ve only found one so far (found two taunts though, ironically lol) - a while skin named “Mercy”:
This is my favorite skin for her. Also the first image is the pose from one of her hidden taunts: “Swing Away”.
