Pigboat,
I'm not sure that you have to be on final.
If your a Cat C aircraft and the Circling minimum is say 6ooFt agl then if you remain in an area prescribed by drawing intersecting circles of 1.7 miles radius from the center of the end of each runway at the airport, not just the runway you are attempting to use, and remain at 600' until the point where you can initiate a constant descent rate, then you are in protected airspace and guaranteed adequate terrain clearance. You could conceivabley be on base.
