Hi Jerry,
You've stimulated an interesting thread and received some high quality
feedback.
My only contribution is to advise you to look carefully at the Maximum
moment of inertia of the combined prop and VP unit if you are seriously
considering fitting a larger diameter Prop.
Rotax advise a maximum of 6000 Kg cm2 (14,328 lb ft2 in old money).
You might wish to discuss this with Martin before making a final decision.
