More power can give you what ever you choose. More Diameter provides more thrust which is what you will need to get off the ground.
More prop pitch will provide you with more speed. More speed will not necessarily get you off the ground.
Pitch Speed Calculator.
In the above pitch speed calculator you can experiment with the props pitch speed by changing KV and prop pitch. This would be the speed of the wind passing through the propeller. Actual plane speed must be lower than this as it will never be 100% efficient in level flight.
