Yes. Thats exactly what I would suggest if you want to make it work. I have the next size up since I have 17gpm capability. Havnt done it yet but my plan is as yours. You can drive a bushog at speed, but cutting torque will be rather low before you surpass your tractor relief pressure setting and get a stall. Taking it easy tho and it could be real handy. Caution on the temptation to use the hog to trim high. ALWAYS keep the bushog tilted so you are not in the plane of the spinning blades.
...Also -- You will have to alternate valving to contol the loader while running the motor - interrupt motor flow while making adjustments. And, you will need a check valve across the motor ports to allow the motor to coast to a stop when valved off to avoid damaging it.
