Advice for Odd-Shaped Drum Practice Area Needed

Hi, I live in a 'Cape' style home, and my drum kit is located in an upstairs room which is irregular shaped -- sort of like a barn. That is, the walls are about 4 feet tall, and then they taper at a 45 degree angle (approx) until meeting the ceiling, which is about 7 feet high. I have sixteen (16) 2' x 4' panels of #703, and I would like to know where to properly place them. I understand that normally, a few stacked in a corner from floor to ceiling work well. However, my corners are a bit different -- perhaps this can work to my advantage? I've seen dozens of ideas for 'regular' rooms, but nothing for my situation. Thanks, Ed
