I'm no pool expert but I can do the basic maths. I'd presume the limiting factor on how much water will pass through a pipe is its cross sectional area, and that these are circular pipes. If so, the area of a 1.5 inch diameter pipe is pi x .75 x .75, and of a 2inch diameter pipe is pi x 1 x 1 . So two of the smaller pipes will have a combined area of 1.125pi sq. inches, more than the single bigger pipe at 1pi sq. inches. Answer From A Pool Contractor Two 1.5" pipes into a single 2" line is acceptable for your flow rates. The flow rate will depend more on your pump than the two 1.5" diameter lines. You could add a third, or even more lines and individually isolate them with ball valves so you can adjust the flow from each as per the requirements of the pool.
