The Camco countertop is a great option. Mounting under the existing countertop eliminates the need to match the contour of the existing counter.
Regarding the ladder relocation with four spring clips, I would be cautious to advise others to use it as a full-load handrail. To qualify, a handrail must be capable of taking 200 pounds of horizontal force, and if that were the case, you could not get a broom-clipped ladder off the wall. I did use cam locks on my ladder, and while I believe it carries the 200 pound test load, I have not actually tested it.
