The issue isn't the suit. Remember that at one point deep sea diving was done in those big bulky suits with the brass helmet and glass windows. In either a space suit or a diving suit the basics is the same, pressure is used to provide a survivable environment. The difference is which direction does the system have to apply that pressure. Underwater, pressure from the environment pushes in and so the suit has to push back out. In space, pressure from inside the suit tries to get out so it has to be held in. From a design stand point that is a very important difference.

though I believe an astronaut could jump in a lake with their suit on and still be able to breathe through their tanks... we're not talking about the Marianus Trench here.
