I also did not want to reduce prop walk with a smaller wheel. And, would'nt the tips be thicker after shortening the blades?
Generally a 2" pitch change on props that sized are not recommended.
It tends to be too much of a deviation from the props core and the results are not typically welcome.
Pitch changes for those extremes are nest suited to a prop change.
