It may also help to think of the entire approach as a way to get you from some altitude down close so you can hopefully land. In other words, no matter if you plan to go straight in or circle, you follow the entire approach until you can descend to land normally (actual reference above). You're just restricted to an MDA depending on whether you circle or go straight in.
If you pass the FAF and suddenly the skies open up and you see the entire airport and you're still 2000' above the threshold, you would probably just want to "circle to land" by using a very normal visual traffic pattern. In that case, the approach did it's job and you didn't have to get anywhere near the mins to do what you want.
Just remember the "point" of the approach and if you're still in IMC you better adhere to the step downs and minimum altitudes at each.
