Correct pipe and pump size

I have a 2hp pump with a 2" intake and 1.5" outflow. I have approx. 2,000 feet of 2" pipe laying around and would like to use it for my sprinkler project. If I were to run 2" line from the 1.5" outflow of the pump as the main water line until I need to downsize the pipe near the rotary heads, would the pressure be effected ? I would be pumping 1.5 into a 2" and then stepping it down to 1.25 and 1" line. Any thoughts?
