Unless you are willing to accept a smaller diameter prop or go with

much longer gear then this will cause real issues with

rotation at takeoff and prop strikes on landings

Yes we know that. Longer fixed gear is not that big of a modification.
Would also improve prop efficiency on tractors.

I was under the impression this discussion was applied to Pushers,

extending fixed gear in a pusher is not an option, the bow is

a custom item made up in molds.

Make a new mold or have the gear bent up out of aluminum plate.
There is an outfit that will do that for you. Since the modulas of
elasticity is higher it will make a better gear anyway. Not only
that it won't melt from brake heat as the stock fiberglass gear
is won't to do.

Good idea. Get one of Ken's tried and true 3:1 cog belt reduction units and have 
Ken lengthen the output shaft by about a foot. Ken could use something like this four
inch output shaft without the planetary to stiffen the output shaft in torsion.

That will make one hell of a pusher PSRU. Could help with the prop-in-wing-wake 
problem.
