They may work. I won't laugh at them but I just did 130 miles of 60% gravel and 10,000' of climbing on traditional deep semi-pista bars with brake hoods in the old low position. (Japanese made. I don't know the brand. Popular with hipsters a few years ago.) I've been struggling with chronic hand/wrist issues from old injuries and using tools. etc. that push my strength. Came home from the weekend and woke up Monday morning with my hands feeling great!
Those tops may be an improvement for my hands for seated climbing like I do a lot of when gravel riding. But I won't give up the drops of a shape from 50 years ago. Comfort and control last weekend on the hairy (and sometimes very rough) descents was excellent.
