I really don't understand what your question is...
If you are "Cleared for the VOR RWY 17 (or VOR A) Approach, Circle to Land Rwy 35," you must first have the circling minimums -- whatever they are -- to start the approach. You can break off the approach to start the circling maneuver any time after the Final Approach Fix, and within the maneuvering area defined for your category of airplane (FAA AIM 5-4-20.b.1). Then, "Pilots should remain at or above the circling altitude until the aircraft is continuously in a position from which a descent to a landing on the intended runway can be made at a normal rate of descent using normal maneuvers." (5-4-20.f)
If you are "Cleared for the VOR RWY 17 Approach," you are NOT cleared to circle and land on any other runway, regardless of weather! If you intend to land on RWY 35 in the first place, you may NOT start the approach until cleared for the circling approach as above.
