Absolutely!
I changed the colors, but I used the CMYK values you provided, and for the P-320, I got a strange light seafoam green color, and the Reflex blue values gave me a magenta color.
So what I did was I just looked up both colors in my Pantone palette in Illustrator.
Keep in mind the colors that you see on the screen are just an approximation of what will actually print using the Pantone colors, as the Pantone colors, most especially Reflex blue are much more vibrant than the CMYK to RGB conversion supports. :-)
Please let me know if there is anything else I can provide.
