My goodness, what a conundrum. How about a compromise, pick out the peas, as you know you want those, and sow the rest ramdomly as you wish. Lucky you to have the space to do either or both. Would peas bare fruit sown this late? Might be ok in one of your famous GH's.
Look on picking out the peas as one of those mindless activities that mum used to set you doing as a little girl, like sorting out the button box. Having sorted they all went back in the same box for next time. I had hours of fun. It even extended to adult motherhood, I love sorting Lego bricks - how sad.
